Elements in group 15 will electrons to obtain a noble gas structure. how many electrons will the element gain or lose in order to obtain a noble gas structure?

Elements in group 15 will gain electrons and it will gain 3 electrons to obtain a noble gas structure.

Explanation:

A noble gas structure is obtained when it completes a full octet around the atom. Meaning it has 8 electrons in its outer shell.

Group 15 is also known as Group 5A or the Nitrogen group. The nitrogen group have 5 valence electrons. Now something to remember about gaining and losing electrons. When the outershell is more than half full, it is more likely to attract electrons to itself. When the outershell is less than half full, it is more likely to lose electrons.

So in the case of group 15, which has 5, it is closer to 8, so it will gain an electron. To complete the octet, it will need 3 more electrons.

explanation:

crosscutting concepts have application across all domains of science. as such, they are a way of linking the different domains of science. they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.

answer; i do believe the correct answer is (river); /// good luck
