∙ 6y agoGroup 7A are the halogens. They have 7 valence electrons and so will easily capture one more. This creates an ANION, which has a negative charge. NO, THEY ARE NOT CATIONS.

What is 7a in the periodic table?
7A is the 17th period in the modern periodic table. It contains halogens.Fluorine,chlorine,bromine are few examples.
What is the usual charge on an ion from group 7A?
The charge that is usually formed by the elements in group 7A is 1-
The Group 7A elements form ions with a charge of?
The charge of group 7A elements when forming ions is -1 (negative 1).
What element have the smallest atomic raduis in Group 7A?
From group 17 (7A), fluorine has the lowest atomic radius.
Characteristic of elements in group 7A?
They are Halogens
What is the ratio of anion to cations in a compound formed by a group 2A metal and a group 7A nonmetal?
1 to 2
What do group 7A elements become when they react with group 1A?
Atoms of column 7A become anions when they react with atoms of group 1A elements, which become cations. Both the cations and the anions are monovalent. The cations and anions together form an ionically bonded compound.
Are Group 7A elements the alkaline earth metals?
Group 7A are not metals.Alkaline earth metals refer to Group 2A.and group 7a is halogens which are non-metals
How might cations in group 1 be separated from cations in group 2?
If your Group 2 cations are calcium, strontium or barium, add a solution containing sulphate ions, i.e. sulphuric acid or the sulphate of the Group I metal that is the Group I cations in your solution. The Group 2 cations will precipitate out with the sulphate ions. If you have beryllium or magnesium cations, then I don't know.

What are the Group 1A and Group 7A elements examples of?
Sodium and Chlorine = Sodium Chloride Potassium and Iodine = Potassium Iodide
What is the group precipitant of group 1 cations?
HCL
In a periodic table that included electron dot diagrams in which column would the diagrams contain more dots Group 3A the boron family or Group 7A the halogens?
group 7A the halogens.
