What are the valence electrons? For s-block and p-block elements show that number of valence electrons is equal to its group number.
Electrons present in the outermost shell of the atom of an element are called valence electrons. 3Li is an s-block element and its electronic configuration is 1s22s1. Since it has one...

On the basis of even-odd of protons and neutrons, what type of nuclides are most stable ?
Nuclides with even number of protons (Z) and even number of neutrons (N) are most stable. These nuclides tend to form proton-proton and neutron-neutron pairs. This impart stability to the nucleus.

The nuclides with odd number of both protons and neutrons are the least stable. Why?
The nuclides with odd number of both protons and neutrons are the least stable because, odd number of protons and neutrons results in the presence of two unpaired nucleons. These unpaired...

Three elements Q, R and T have mass number 40. Their atoms contain 22, 21 and 20 neutrons respectively.
Mass number (A) = Number of protons (Z) + Number of neutrons (N). A = Z + N ∴ Z = A – N For the given three elements, A = 40. Values of their...
