Effective nuclear increases as we move to the right across a row in the periodic tablec. Effective nuclear charge remains relatively constant as we move to the right across a row in the periodic tabled. effective nuclear charge increases and decreases at the regular intervals as we move to the right across in the row periodic table

Respuesta :

Answer:

The effective nuclear charge increases as we go down a column.

Explanation:

mastering chemistry

Effective nuclear increases as we move to the right across a row in the periodic table is true about Effective Nuclear Charge.

What is Effective Nuclear Charge?

The effective nuclear charge refer to the total amount of positive charge that surround electron in a polyelectronic atom.

It can also be define as the total charge that is present in the nucleus of protons in an atom. It also have the same value as the number of atoms.

Therefore, Effective nuclear increases as we move to the right across a row in the periodic table is true about Effective Nuclear Charge.

As the atomic radius decreases across a period and also increases down a group, effective nuclear charge increases as electron shielding is constant.
