Answer the following questions:

i) Which atom is likely to form anion?

ii) Which atom is likely to form cation?

iii) What will be the valency of A?

iv) What is formula of the compound formed by A and B?

v) Will the compound formed have a high or low melting point?​

Answer 1

Answer:

1- atom A .2- atom B 3- A=+2 . 4 - AB

Explanation:

1.its atomic number is 30 so it can lend 2 electrons and complete octet E. C.

2.it gains 2 electrons and gets negative charge

3.+2 ( same answer as 1)

4.AB because +2 , -2 gets simplify and become 0
