Answer

In 1932, Chadwick made a fundamental discovery in the domain of nuclear science: he proved the existence of neutrons – elementary particles devoid of any electrical charge. In contrast with the helium nuclei (alpha rays) which are charged, and therefore repelled by the considerable electrical forces present in the nuclei of heavy atoms, this new tool in atomic disintegration need not overcome any electric barrier and is capable of penetrating and splitting the nuclei of even the heaviest elements. Chadwick in this way prepared the way towards the fission of uranium 235 and towards the creation of the atomic bomb. For this epoch-making discovery he was awarded the Hughes Medal of the Royal Society in 1932, and subsequently the Nobel Prize for Physics in 1935.

Answer:

A.outer-shell electrons of one atom are transferred to the inner electron shells of another atom.

Explanation:

In covalent chemical bond, outer shell share pair of electrons to fill both atoms outer shell. Covalent bond can be polar and non-polar. Hydrogen and carbon bonding is example of non-polar bonds; while hydrogen bonding with chlorine is polar covalent bond example
