Question

2. Geometrically represent the following elements.
• Ca- A-40, Z-20
• F-A-19, Z-9
• N-A=14, Z-7​

Answer 1

Answer:

• CA - A-40,40,Z-20
• F-A-19,

Answer 2

Ca-

Atomic no.(Z)-20

Atomic mass(A)- No. of protons + no. of neutrons

=> 20+20=40

F:

Atomic no.(Z)-9

Atomic mass(A)- No. of protons + no. of neutrons => 9 + 10 = 19

N:

Atomic no.(Z)-7

Atomic mass(A)- No. of protons + no. of neutons

=> 7 + 7= 14
