Answer 15

No, no two electrons have the same quantum numbers

Question 16

When is an electron configuration considered stable?

Answer 16

When the subshells (orbitals) are full - like the noble gases

Question 17

Describe an atom in its ground state.

Answer 17

An atom in its ground state has the lowest possible energy.

Question 18

Describe an atom in its excited state.

Answer 18

An atom in its excited state has gained energy

Question 19

What happens when a photon of light is emitted?

Answer 19

A photon of light emits when an electron goes from its excited state back to ground state

Question 20

On the periodic table which direction does ionization energy increase?

Answer 20

Ionization energy increases as you move from bottom to top and from left to right. Fluorine has a very high ionization energy, Fr has a very low ionization energy

Question 21

What is electronegativity?

Answer 21

Electronegativity is the ability of an atom to attract electrong

Question 22

Does electronegativity increase or decrease as the atomic number of an element increases within the same period of the periodic table?

Answer 22

Electronegativity increases as atomic number increases. It increases from left to right across the periodic table
