structure of atom mcq

Calcium has 20 electrons. These occupy K,L,M, and N shells. Which shell or shells are incomplete 1) L,M,N shells 2) M,N shells 3) N shells 4) K,L,M,N shells

The size of an atom is decided by 1) mass of the atom 2) no. of protons 3) no. of protons and neutrons 4) no. of electrons

Isobars have 1) same no. of protons and different electron 2) different number of protons and neutrons 3) same no. of electrons and neutrons 4) same no. of neutrons

Isotopes are 1) atoms of same element 2) atoms of different elements 3) molecules of same element 4) radicals of the same element

Atomic number of A is 10 and element B is 11. Which statement about A and B is correct 1) Both are chemically inert 2) B is chemically inert 3) B is more reactive than A 4) A is more reactive than B

According to Bohr Burry the maximum number of electrons that can be accommodated in each atomic orbital is 1) 8 2) 2 3) 10 4) 6

Gold foil was used in Rutherford's scattering experiment because it 1) has high refractive index 2) has high density 3) is highly malleable 4) is high ductile

The region in space where there is a finite probability of finding electron is 1) Atomic number 2) Atomic orbital 3) Atomic particle 4) Ground state

Bohr's model could not account for 1) Seebeck effect 2) Raman's effect 3) Condensation effect 4) Zeeman effect
