What happens to the size of the metal atoms as you go down group I (alkali metals)? Why is this so?

Answer 1

As you go down group I (alkali metals), the size of the metal atoms will be larger. This is because the number of electrons (the atomic number) of each atom gets larger as you go down, thus the electrons occupy more shells, thus they cause the diameter of the atom larger.

Answer 2

The alkali metals have the biggest atomic radii of their classes contained in the periodic table. it really is because there's a unmarried electron contained in the outer maximum shell of each and every alkali metallic, and it really is thus far way from the nucleus of the atom, that it really is genuinely lost. subsequently they genuinely type positive good ions. the convenience that the valence elctron is lost will boost because the atomic radii will boost, it really is down the crew. Now a good melts even as the kinetyic capacity of molecules will change into large adequate to triumph over the intermolecular forces(Vanderwals) preserving them fixed, so your good will commence to soften.So, the quantity of capacity had to modify a good to a liquid alkali decreases down a set the more effective the radii get, the weaker the gorgeous forces change into.

Answer 3

i think they get bigger b/c they have more electrons and the "shielding effect" which is the inner ones blocking the outer ones from the effect of the protons

Answer 4

They gain protons and neutrons in the nucleus, and electrons in the orbitals, and become electroPOSITIVE. The OTHER end is electroNEGATIVE.
