Answer:
(n, l, m sub l, m sub s)
N: principle quantum number (1,2,3,4,etc)
l: angular momentum quantum number, the shape (l has to be at least 1 less than n, but can be 0 depending on n)
M sub l: magnetic quantum number (l determines this number)
M sub s: spin quantum number (can only ever be 1/2 or -1/2)
Explanation:
The principle, azimuthal, magnetic, and spin quantum numbers specify the principle shell, the shape of the orbital, the number of orbitals, and electron spin respectively.
What are the quantum numbers?The set of numbers that describes the position and energy of the electron are called quantum numbers. Four quantum numbers are principal, azimuthal, magnetic, and spin quantum numbers.
Principal quantum numbers (n) designate the principal electron shell of the atom and the most probable distance between the nucleus and the electrons. A larger value of the principal quantum number indicates a large distance between the electron and the nucleus.
The azimuthal quantum number (l) describes the shape of an orbital in which an electron is present. Its value is equal to the total number of angular nodes in that orbital.
The magnetic quantum number describes the total number of orbitals in a subshell and the orientation of these orbitals. The value of the spin quantum number (s) offers the direction in which the electron is spinning and it has only two possible values +½ and -½.

how did dalton advance the atomic philosophy proposed by democritus
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
Dalton turned Democritus' views on atoms into a scientific theory by employing experimental methods. Atoms can join or detach during chemical processes, but they never transform into a different atom.
Dalton was an excellent polymath, a natural philosopher, and a real scientist. His thorough investigations prompted him to suggest an early atomic theory for which exceptions would be difficult to uncover today:
Dalton offered the following:
Atoms are microscopic particles that make up elements. Atoms of the same element have the same size and mass; however, atoms of other elements have varying sizes and masses when compared to atoms of other elements. Subdivision, creation, and destruction of atoms are all impossible.
All of these ideas were developed after a great deal of testing. Other researchers may replicate his work, and new findings could be included into this atomic idea.
Democritus, on the other hand, was a 5th-century BC Greek philosopher. He conducted no experimental work as far as we know, and none of his publications have survived. He postulated that matter was made up of a single indivisible element known as an atom; the word atom originates from the Greek word oos, which meaning "uncuttable" or "indivisible." So the name atom might be a homage to Democritus.

Does sodium (Na) and argon (Ar) on the periodic table have similar properties? Explain in terms of location on the periodic table
Sodium (Na) and Argon (Ar) on the periodic table does not have similar properties.
PERIODIC TABLE:
Periodic table is the organized table that showcases the position of elements. The periodic table is organized into groups and periods. Groups of the periodic table is in a vertical format labeled 1 - 7 while the period is in a horizontal format labeled 1 - 7. Elements in the same group have the same number of valence electrons and hence, possess similar chemical properties. Sodium (Na) belongs to group 1 while argon is a noble gas, hence, they are not in the same group of the periodic table and cannot have same properties.Learn more at: https://brainly.com/question/24089206?referrer=searchResults

draw the skeletal structure of the alkyl halide that forms the following alkene as the only product in an elimination reaction. you do not need to show lone pairs.
The alkyl halide that forms the alkene shown as the only product in an elimination reaction is bromomethyl cyclohexane.
An elimination reaction is a reaction in which two atoms are removed to create a double bond. Elimination reaction is a type of reaction that is common to alkyl halides.
In this reaction, a hydrogen atom and a halogen atom are both removed to yield a double bond. The structure of the product depends on the structure of the reactant alkyl halide.
Bromomethylcyclohexane shown in the image attached yields the alkene product in the image attached as the only product when it undergoes elimination reaction.

Which of the following are properties of compounds formed by covalent bonding (Select all that apply)
1. When you dissolve an covalent compound in water, the solution does not conduct electricity.
2. Covalent compounds often have lower melting points than ionic compounds.
3. When you dissolve an covalent compound in water, the solution conducts electricity.
4. Covalent compounds form when combining two or more nonmetal atoms.
5. Covalent compounds form when combining a two metal atoms.
6. Covalent compounds form when combining a metal atom with a nonmetal atom.
The properties of covalent compounds are option 2, 3 and 4. Covalent bonds are weaker than ionic bonds.
What are covalent bonds?Covalent bonds are formed by sharing electrons between two atoms. Non metals with comparable electronegativities forms covalent bonds. They are weaker than ionic bond. Thus have lower melting point.
Melting point depends on the bond strength that's why covalent compounds have lower melting point compared with ionic bonds.
Polar covalent bonds can conduct electricity when dissolved in water because of the presence of free electrons. Thus option 3 is correct.
Hence, the properties in option 2, 3 and 4 are correct for covalent compounds.

suppose that hypothetical element Jovian occurs as three isotopes with mass numbers 44, 46, and 48 respectively. If, in nature, Jovian occurs as Jovian-44 approximately 22.4% of the time, and as Jovian-46 approximately 44.0% of the time, what is the best value to use as the atomic mass of Jovian?
Answer:
46.2 amu
Explanation:
The average atomic mass of an element can be determined using the percentage abundance and mass of its isotopes. The average atomic mass of the hypothetical element Jovian is 46.2 amu.
What is average atomic mass?Most of the elements have two or more isotopes in nature with different percentage abundance and mass. The average atomic mass of the element is then calculated using the formula written below:
Average atomic mass = % abundance /100 × mass of isotope 1 + % abundance /100 × mass of isotope 2 + .....
Given the mass % abundance of Jovian -44 = 22.4 %
Jovian- 46 = 44 %
Jovian -48 = (100 - (44 + 22.4)) = 33.6 %
Average atomic mass of Jovian = ( 22.4 /100 × 44 ) + ( 44 /100 × 46) + ( 33.6 /100 × 48 ) = 46.2 amu
Therefore, the average atomic mass of the hypothetical element is 46.2 amu.

Compared to the atomic radius of sodium, the atomic radius of argon is smaller. This is a result of
The atomic radius of Argon is smaller than the atomic radius of sodium because the effective nuclear charge increases as we move left to right in a period.
What is the atomic radius?The atomic radius can be described as the shortest distance between the center of the nucleus of the atom and the outermost shell of the atom. An atomic radius can also be defined as half the distance between two atoms of the same element bonded together.
In general, the atomic radius of an atom reduces as we move from left to right in a period on the periodic table because while moving from left to right in a period, there is an increase in the effective nuclear charge. In periods, the valence electrons enter in the same outermost shell.
The atomic radius of atom increases when we move down a group because of the addition of a new principle shell.
Sodium is present at beginning of the third period and the Argon is present at the end of the same period. Therefore, Argon experiences a more effective nuclear charge than sodium so it has a smaller atomic radius.
