Write the ground state electron configuration of zn using the noble-gas shorthand notation.

The shorthand noble gas electronic configuration of Zn is [Ar] .

The Zn belongs to period 4 of the periodic table. It has the atomic number 30. It states that it has 30 electrons. The electrons are distributed according to the octet rule:

For the noble gas shorthand notation, the nearest noble gas is argon, with electronic configuration:

So, the electron configuration of Zn using the noble-gas shorthand notation will be:

[Ar]

the answer is a. co2, this would be colder than the : )

explanation:

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
