Question

The description of atomic particle of two element X and Y is given:-
Protons- 8. 8
Neutron- 8. 9
Electron- 8. 8
i) what is the atomic no. Of Y ?
ii) what is the mass no. of X?
iii) " is the relation between X &Y
iv) which element does X represent?
v) write the electronic configuration ofX?
vi) write the cation /anoin formed by the Y element ,?

Answer 1

hi mate your answer

1)the atomic number of y is 8

2)the atomic mass number of x is 16

3)yes x and y has same atomic number but different atomic mass number.means they are isotopes of same element.

4)the name of x is oxygen

5)electronic configuration of x-

(2,6)

6)the ion formed by y is 2^-

hope that it will help you
