Question

The periodic table contains a lot of information in it. With the help of that
information calculate the number neutrons present in the non-metallic elements of
the periodic table.
​

Answer 1

Answer:

Explanation:

Within each element square, information on the element's symbol, atomic number, atomic mass, electronegativity, electron configuration, and valence numbers can be found. At the bottom of the periodic table is a two row block of elements that contain the lanthanoids and actinides.

NUMBER OF NEUTRONS= MASS NUMBER - ATOMIC NUMBER

MASS NUMBER = NUMBER OF PROTONS + NUMBER OF NEUTRONS

ATOMIC NUMBER=  NUMBER OF PROTONS

For example take oxygen (O)

NO. OF NEUTRONS = MASS NUMBER - ATOMIC NUMBER

                                  = 16-8

                                  = 8
