Answer:

Chromium (Cr) is a transition metal

Explanation:

Transition metals are a series of elements present in the center of the periodic table. They are also referred to as the 'd-block' elements as it is the d-orbital that gets progressively filled with electrons with the increase in atomic number.

Based on the given examples:

1) Francium (Fr) is an alkali metal: group 1

2) Beryllium (Be) is an alkaline earth metal: group 2

3) Chromium (Cr) is a transition metal : group 6

4) Gallium (Ga) is a post-transition metal: group 13

5) Bismuth (Bi) is also a post-transition metal: group 15

Give the ground-state electron configuration for silicon (SiSi) using noble-gas shorthand. Express your answer in condensed form
nydimaria [60]

Answer:

[Ne] 3s² 3p²

Explanation:

Silicon atoms have 14 electrons. The ground state electron configuration of ground state gaseous neutral silicon is 1s²2s²2p⁶3s²3p².

Using noble gas shorthand, the electronic configuration is reduced to;

[Ne] 3s² 3p². Ne s the nearest noble gas to silicon, Ne contains 8 electrons, this means there's still 4 more electrons to fill. The s orrbital can only hold 2, hence the reaing two is transferred to the p orbital.
