Question

Oxidative stress causes a molecule to

		gain a proton
		loss an electron
		lose a neutron
		gain an electron

Answer 1

Oxidation : loss of electron is called oxidation.

e.g. sodium - (Na) = atomic number =11

electronic configuration : 1s² ,2s² ,2p⁶ ,3s¹ . ground state electronic configuration.

in excited state of electronic configuration i.e. Na⁺¹ electronic configuration is as follows

1s²,2s²,2p⁶,3s⁰.

here, sodium losses one electron from outermost shell therefore its oxidation state is +1.

From example it is clear that-

oxidative stress causes a molecule to a - LOSS AN ELECTRON
