Developed the Bohr model of the atom, in which he proposed that energy levels of electrons are discrete- Niels Bohr

Discovery of energy quanta made him the originator of quantum theory -Max Plank

Formulated the wave equation; stationary and time-dependent Schrödinger equation- Erwin Schrödinger

Best known to the general public for his "mass–energy equivalence formula" ; E = mc^2-B Albert Einstein

Postulated the wave nature of electrons and suggested that all matter has wave properties- Louis de Broglie

Explanation:

All the names mentioned above contributed towards the development of the wave mechanical model of the atom. Their names were matched with their contributions as required by the question.

when it gains or loses electrons

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
