One
Phosphorous
There are different electrons in the outer shell of each element.
Carbon need to obtain four more electrons in order to obtain a noble gas configuration.
Group one elements are the most reactive with group 7 elements as it is the easiest way for the elements to complete their outer shell as the group one element gives its extra electron to the group 7 element and then the group 7 element has a full shell too.

Phosphorous
Elements in group VIA (6A) also called group 16.
Elements in Group 1 of the periodic table have one electron in their outer shell, while elements in Group 2 have two electrons in their outer shell. This configuration makes these elements more stable and likely to form ions with a positive charge by losing these outer electrons to achieve a full outer shell.
group 18
There are different electrons in the outer shell of each element.
Carbon need to obtain four more electrons in order to obtain a noble gas configuration.
An oxygen atom has six (6) electrons in its outer shell.
There are different electrons in the outer shell of each element.
Six in the outer (2nd) shell
Valence electons
Group one elements are the most reactive with group 7 elements as it is the easiest way for the elements to complete their outer shell as the group one element gives its extra electron to the group 7 element and then the group 7 element has a full shell too.
As is a p block element in period 4 and group 5A, so it has 5 valence (outer) electrons (4s2 4p3).
