Question #905c7

Answer 1

Isoelectric means equal electric.

Explanation:

The term "isoelectronic" means "equal electric" or equal charge.

Isoelectronic species are atoms or ions having the same, or equal number of electrons. We can explore that the isoelectronic species have the same number of electrons, they are different in their physical and chemical properties.

`Na^(+1)`, `Mg^(2+)` and `Al^(3+)` have same eletronic configuration called isoelectronic configuration.

Answer 2

See below.

Explanation:

Isoelectric means that a molecule carries no net electrical charge in average.

For example, a molecule of glycine `NH_2CH_2COOH` is in the equilibrium state:
`NH_2CH_2COO^- ""+ 2H^+ ⇄ NH_3^+CH_2COO^- ""+H^+ ⇄ NH_3^+CH_2COOH`

In the formula above, `NH_3^+CH_2COO^-` is the isoelectric species.

The `pH` at which a molecule is isoelectric is called isoelectric point.
