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.
a negative 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-.
The elements that lose electrons and form positive ions are called metals. They will lose the electrons from their highest levels of energy to gain a more positive charge and form positive ions.
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.
lose 2 electrons and form ions with a 2+ charge.
When group 1A elements form ions, they form cations with a +1 charge.

no
The elements that lose electrons and form positive ions are called metals. They will lose the electrons from their highest levels of energy to gain a more positive charge and form positive ions.
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.
a negative charge
The Group 7A elements, also known as the halogens, typically form ions with a charge of -1. This is because they only need to gain one electron to achieve a stable electron configuration similar to the nearest noble gas.
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-.
All the listed elements form ions with a charge of 1, if "1" is taken as the absolute value of the charge on the ion. For fluorine, however, the corresponding ion has a charge of -1.
The elements that lose electrons and form positive ions are called metals. They will lose the electrons from their highest levels of energy to gain a more positive charge and form positive ions.
