Question

neutron,electron and proton of HNO3​

Answer 1

Answer:

Explanation:

As we know

Nitrate =

total no of proton = atomic number

= 7 + 8

= 15p

now as there is a negative charge so total no of electron = total no. of proton + |charge|

= 15 + |-1|

= 16e

now as Netron + Proton = mass no.

then 14 = 7 + n(for nitrogen)

16 = 8+ n ( for oxygen)

there for total no. of netron = 8+7 = 15n
