The charge of group 7A elements when forming ions is -1 (negative 1).
positive charge.
Elements in group 1, also known as the alkali metals, typically form ions with a +1 charge by losing one electron. This is because they have one electron in their outermost energy level, making it easier for them to lose that electron to achieve a stable electronic configuration.
1: 1+ 2: 2+ 13: 3+ 14: 4+/- 15: 3- 16: 2- 17: 1- 18: Neutral Transition metals (elements between groups 2 and 13) are able to have varied charges that there is no real rule for.
Group 1 elements a.k.a. Alkali metals lose 1 electron to form 1+ ions
Group that tend to form -1 ions include group VIIA
lose 2 electrons and form ions with a 2+ charge.
When group 1A elements form ions, they form cations with a +1 charge.

Elements in Group 2 of the periodic table form ions with a charge of 2. This group includes elements such as calcium, magnesium, and barium. When these elements lose two electrons, they form ions with a +2 charge.
The group 2 elements form ions with a 2+ charge. For example, Mg2+ and Ca2+. The group 16 elements form ions with a 2- charge. For example, O2- and S2-.
Elements in Group 1 (alkali metals) readily form ions by losing one electron to achieve a stable electron configuration. This is due to their low ionization energy, which makes it easier for them to lose electrons and form positively charged ions.
Group 1 elements a.k.a. Alkali metals lose 1 electron to form 1+ ions
Group that tend to form -1 ions include group VIIA
Group 1 elements (alkali metals such as sodium, potassium) lose 1 electron to form ions with a +1 charge.
When Group 2A elements form ions they lose the electrons in their outer shell. In doing so they form positive ions known as cations.
