Answer:

wait I send ans this question

Answer 2

Answer:

a.O - protons = 8. A = 16

electrons = 8. Z = 8

nuetrons = 16-8 = 8

b.Cu - protons = 29 A = 64

electrons = 29 Z = 29

nuetrons = 64-29 = 35

c.P - protons = 15. A = 31

electrons = 15. Z = 15

nuetrons = 31-15 = 16

d.K - protons = 19. A = 38

electrons = 19 Z = 19

nuetrons = 38-19 = 19

e.Ti- protons = 22. A = 47

electrons = 22. Z = 22

nuetrons = 47-22 = 25

*A is atomic mass and Z is atomic number.

Thank you.....
