The Group 7A elements form ions with a charge of?
The charge of group 7A elements when forming ions is -1 (negative 1).
How many electrons occur in the valence level of Group 7A and 7B elements. Why are they different?
7 in 7A 2 in 7B The 7A are representive elements The 7B are transition elements
What are the Group 1A and Group 7A elements examples of?
Sodium and Chlorine = Sodium Chloride Potassium and Iodine = Potassium Iodide
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-
What is the general valence shell configuration for the elements in group 7A?
Valence electron configuration in group 7A (halogens): ns2, np5 in which n=2, 3, 4, 5, ... etc. Starting with fluorine, F, electron configuration: (1s2), 2s2 2p5 (non valence electrons in () brackets)
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

Elements from which group are necessary to make halide?
Group 17 (7A) elements are considered halides. Fluorine, Chlorine, etc...
The highly reactive elements in group 7A which are known for forming salts are the?
Halogens
Which group of elements reliably forms acids when combined with hydrogen?
Group 17 (7A), the halogens.
When Group 7A elements in a periodic table form ions they lose or gain protons?
The elements in group 7A or 17, gain one electron during ionic bonding, or share one electron when undergoing covalent bonding.
When Group 7A elements in a periodic table form ions do they lose or gain protons?
The elements in group 7A or 17, gain one electron during ionic bonding, or share one electron when undergoing covalent bonding.
What other group on the periodic table is most likely to react with elements in group 1A?
If you meant to say "elements ARE most likely to bond with," which is probably what you meant, then the answer would be 7A(or 17), also called the Halogens. "Halogen" actually means "salt-forming." When you take a chlorine (7A) and sodium (1A), you end up with table salt! ---- In a nutshell, the answer is Group 7A, or 17.
