Question

The symbol used for oxygen is O there are 8 protons and 8 neutron in its nucleus from this determine the atomic number Z and mass number A of oxygen and arrange these in a conventional symbol

Answer 1

Answer:

Atomic number = no. Of protons or no. Of electrons.

: . Z = p =e

Mass no. = no. Of neutrons +no. Of protons

: . A=n+p

Explanation:

Now,

Oxygen's

p=8

e=8

Hence,

Z = 8

A= p + n

A=16

It's conventional symbol

16

O

8

Answer 2

Answer:

Atomic mas number

proton. ➕ neutron

8 ➕ 8

16

16 o

8
