Question #905c7

2 Answers

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.

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.
