As you move down a group in the periodic table atomic size generally
1 answer:
Answer:-
Increases
Explanation:-
Atomic size refers to the distance between the nucleus and the outermost valence shell.
As you move down a group, a new shell is added. So the distance of the valence shell increases from the nucleus as we go down a group.
Thus as you move down a group in the periodic table atomic size generally

<h3>What is moles?</h3>
Mole, also spelled mol, in chemistry, a standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, or other specified particles.
The mole designates an extremely large number of units, 6.02214076 × . The General Conference on Weights and Measures defined the mole as this number for the International System of Units (SI) effective from May 20, 2019. The mole was previously defined as the number of atoms determined experimentally to be found in 12 grams of carbon-12.
The number of units in a mole also bears the name Avogadro’s number, or Avogadro’s constant, in honour of the Italian physicist Amedeo Avogadro (1776–1856). Avogadro proposed that equal volumes of gases under the same conditions contain the same number of molecules, a hypothesis that proved useful in determining atomic and molecular weights and which led to the concept of the mole.
