Valence Electrons And Energy Levels Of Atoms Of Elements

Question 1

What do electrons determine?

Answer 1

How an atom react with another atom or molecule

Na + H20

Question 2

An electron can make a difference in ________ of an atom

Answer 2

Properties

Exp Na electron in last orbital- shiny explosive

W out the last electron we can consume it

Question 3

Lewis dot diagram represents

Answer 3

They’re valence electrons

Question 4

Octet has

Answer 4

8 valence electrons

S& p orbitals are filled with electrons so they are extremely stable

Question 5

As you move down the period what happens?

Answer 5

The number of orbitals increase

Question 6

Having an outer electron flying alone on the orbital makes the atom

Answer 6

Chemically unstable

Question 7

The ability for the outer valence electron to chemically react is dependent on

Answer 7

How easily it can get rid of the other electron

Question 8

The more orbitals an atom has and a line valence electron

Answer 8

The higher it will react!

Li—- sizzle in water because it’s valence electron is close to the nucleus/ harder to give up

But when K goes in water it blows up because the valence electron is farther from its nucleus and can loose the electron easily

Question 9

The period represent the energy level _______ will have

Answer 9

Valence Electrons

Question 10

Group represents

Answer 10

Valence electrons
