However, as per the old terminology, group VIIA (or now group 17) are halogens and will form anions.

The Group 7A elements form ions with a charge of?
The charge of group 7A elements when forming ions is -1 (negative 1).
What type of ions do the elements of group 1 form?
Group 1 elements are the alkali metals, which form ions wih a 1+ charge.
What group of elements tends to form negative ions that have a -1 charge?
Group that tend to form -1 ions include group VIIA
When group 2a elements form ions what happens?
When group 2A elements form ions, they lose two electrons. Some examples of group 2A elements include radium and magnesium.
What kind of elements can form ions with more than one charge?
Transition elements are the major group of elements with this property.
The Group 7A elements form ions with a charge of?
The charge of group 7A elements when forming ions is -1 (negative 1).
What type of ions do the elements of group 1 form?
Group 1 elements are the alkali metals, which form ions wih a 1+ charge.
Do elements in group 1 readily or rarely form ions?
Elements of group 1 readily form ions having a charge of +1.
When group A elements form ions they?
lose 2 electrons and form ions with a 2+ charge.
What are the charges of ions in group1A?
When group 1A elements form ions, they form cations with a +1 charge.
What group of elements tends to form negative ions that have a -1 charge?
Group that tend to form -1 ions include group VIIA
When an atom becomes on ion with a two-charge the atom?
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-.
When group 2a elements form ions what happens?
When group 2A elements form ions, they lose two electrons. Some examples of group 2A elements include radium and magnesium.
What kind of elements can form ions with more than one charge?
Transition elements are the major group of elements with this property.
Why atoms of group 0 elements do not form ions?
why atoms of group 0 elements do not form ions
When a group 2A elements form ions they?
When Group 2A elements form ions they lose the electrons in their outer shell. In doing so they form positive ions known as cations.
Elements in group 1 of the periodic table lose one electron to form ions with what?
These cations have the electrical charge +1.
