Refer the picture and please provide a right answer for each ​

Answer 1

Answer:

1) yes hydrogen need to achieve noble gas helium where it k shell should have 2 electrons like helium so therefore,needs one electrons.

2)yes ,oxygen needs two electrons because k,l shell has 2 and 6 respectively but 6 electrons which should be 8 like neon to be Nobel gas.so it needs two electrons.

3)yes nitrogen gas atomic number is 7 so electronic configuration will be 2,5 so to achieve 8 electron in l shell it need 3 electron.

4) electronic configuration of carbon will be 2,4 so it need more 4 electrons to achieve noble gas .

5) electron configuration of calcium Is 2,8,7 so m shell needs one electron to achieve stable position like argon.
