Answer:
electrons are less than 1 amu, they are also negative charged. they are very small too
Answer: Option (b) is the correct answer.
Explanation:
The elements which have excess or deficiency of electrons will react readily.
Atomic number of Mn is 25 and electronic configuration of
is [Ar]
. This configuration is stable.
Atomic number of Cr is 24 and electronic configuration of
is [Ar]
. This configuration is not stable.
Atomic number of Fe is 26 and electronic configuration of
is [Ar]
. This configuration is stable.
Atomic number of Cu is 29 and electronic configuration of
is [Ar]
. This configuration is not stable.
Atomic number of Al is 13 and electronic configuration of Al is
. This configuration is not stable.
Atomic number of Ba is 56 and electronic configuration of
is [Kr]
. This configuration is stable.
Atomic number of Mg is 12 and electronic configuration of
is
. This configuration is stable.
Atomic number of Sn is 50 and electronic configuration of Sn is [Kr]
. This configuration is stable.
Thus, we can conclude that out of the given options, only Fe and
reactants would lead to a spontaneous reaction as they have incomplete sub-shells. Therefore, in order to gain stability they will readily react.
Amino acids.
Amino acids group together to form proteins. Enzymes are protein in nature. Thus the substrate is an amino acid.

The environmental change that occurs faster is definitely volcanic eruption. It may happen in an instant and destroy everything in its way, whereas the process of regrowth of forest after volcanic eruption is a slow one.
