Answer 18

group

Question 19

how are groups different than periods?

Answer 19

groups: valence electrons
periods: energy levels

Question 20

Answer 21

they have the same number of protons

Question 22

what determines an atom’s group?

Answer 22

how many valence electrons it has

Question 23

what determines the period an atom is found in

Answer 23

number of energy levels

Question 24

location of protons, neutrons, and electrons and what charge do they have

Answer 24

protons: positive and nucleus
neutrons: no charge and nucleus
electrons: negative and energy levels

Question 25

remember APE MAN

Answer 25

atomic number = protons = electrons
