Group 1 elements (alkali metals) typically form 1+ cations by losing one electron to achieve a stable electron configuration. These elements include lithium, sodium, potassium, rubidium, cesium, and francium.

Why do elements in group 2 have an oxidation number of plus 2?

Elements in group 2 have an oxidation number of +2 because they readily lose two electrons to achieve a full outer shell, which is the most stable electron configuration. This results in a +2 oxidation state as they become positively charged cations.

What is oxidation state of mg plus plus?

The oxidation state of Mg2+ is +2. Magnesium typically forms cations with a +2 charge by losing 2 electrons.

What is lithium's charge?

A lithium ion has a charge of +1

Ions with a 2 plus charge?

Ions with a 2 plus charge are called cations. They have lost two electrons, resulting in a positive charge. Examples include calcium ion (Ca²⁺) and iron(II) ion (Fe²⁺).

How many electrons occur in the valence level of Group 7A and 7B elements. Why are they different?

Group 7A elements have 7 electrons in their valence level, while Group 7B elements have 17 electrons in their valence level. This difference occurs because elements in Group 7A have 7 valence electrons, while elements in Group 7B have 7 valence electrons plus the 10 additional electrons in the d sublevel which contributes to a total of 17 valence electrons.
