Question

We are metals. We have ________________ electrons in the last shell and we loose electrons from last shell to form _______ ions.

a. 1,2,3 - positive
b. 4,5,6 - positive
c. 5,6,7 - positive
d. 5,6,7 - negative ions​

Answer 1

Answer:

option A

Explanation:

metal have a tendency to form positive ions by donating electrons to other atoms this phenomenon is called as electopositivity.

To loose electrons from last shell elements must have 1 or 2 or 3 electrons i.e less than 4 electrons ( elements can't donate electrons after that for eg. Carbon shares electrons which have 4 electrons in the last shell and after that elements accept electrons from other atoms for eg. Fluorine has 7 electrons in the last shell to complete the octet it accept one electron.)

hope I was clear.

If u understood then pls mark as brainliest
