Question

Element x,y and z have atomic number6,9 and 12 .a forms an anion

Answer 1

Answer:

x and y

Explanation:

An anion is formed when the no. of electrons ian an ion are more tahn the no. of protons. That is- when the atom gains electrons.

For x atomic no. = 6

so, electronic configuration of x = 2,4

To complete an octet, x will need to gain 4 electrons.

Similarly,

Electronic configuration of y = 2, 7

To complete an octet, y will need to gain one electron.

Electronic configuration for z= 2,8,2

To complete an octet, z will need to loose 2 electrons.

Thus, only X and Y will form anions.

Answer 2

Explanation:

Element Y with atomic number 9 would form an anion and element Z with atomic number 12 would form a cation. ... Element x with 'atomic number' 6 is carbon, y with 9 is fluorine, and z with 12 is magnesium.
