Question

How many protons, neutrons, and electrons are there in a neutral atom of 97tc (technetium-97)?

Answer 1

Techneutim(Tc) has 43 protons, 43 electrons and 54 neutrons.

Answer 2

Protons = Electrons = 43

Neutrons = 54

Step-by-step explanation:

Technetium is transition metal and belongs to the 5d-series in the periodic table. Tc- 97 has an atomic number Z = 43 and Atomic mass A = 97

For a neutral atom:

Atomic number = number of protons = number of electrons

Atomic mass = number of protons + neutrons

For Tc-97:

Z = 43, therefore

Protons = 43

Electrons = 43

A = 97

i.e. 97 = 43 - neutrons

# neutrons = 97 - 43 = 54
