Question

The nucleus of nitrogen contains 9 neutron. Find its charge number if it's mass number is 16.I mark brilliant

Answer 1

Step-by-step explanation:

mass no=number of nuetrons+number of protons

16=9+p

16-9=p

7=p

no of protons (p)=no pf neutrons=atomic number

7=7

electronic configuration=2,5

its charge number is -1

valency=(8-5)=3

Answer 2

Answer:

Charge= -1

Step-by-step explanation:

Since neutron number is 9 and we have mass number equals 16 therefore number of protons shall be 7 and as 7 is greater than 4 therefore charge shall be negative and valency shall be positive
