Question

in 88 Ra 226 nucleus there are ?

Answer 1

Hey there!

$^{88} Ra _{226}$

Atomic number ( Z) = 88 .
Mass Number ( A) = 226 .

We know that,
Number of neutrons = A - Z = 226 -88 = 138
Number of Electrons = Z=88
Number of protons = Z = 88 .

In atom, There are three sub atomic particles. Namely , Electrons ,Protons and Neutrons.

Electrons constitute negative charge while Proton has Positive charge and Neutron has no charge.

Electrons revolve around the Nucleus. Protons and neutrons are present in Nucleus. Nucleus overall consists Positive charge . The attraction between Electrons and Protons make electrons to revolve in definite path.

Atomic number is the Number of electrons present or Protons present. Mass number is the Sum of protons & neutrons.

Now, In Nucleus of $^{88} Ra _{226}$ , There are 88 protons and 138 neutrons.

Hope helped!
