Is group 7A cations?
Group 7A cations refer to the cations of Group 7A elements in the periodic table, also known as the halogens. Some common examples of Group 7A cations include fluoride (F-), chloride (Cl-), bromide (Br-), and iodide (I-).
The Group 7A elements form ions with a charge of?
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.
What is the charge on an ion in group 17?
protons and electrons are equally charged except that protons are positively charged and electrons are negatively charged, as there are more protons in this example there is a positive net charge
How many valence electrons does a Chlorite ion have?
ClO2− = 7+6(2)+1=20-------------------------------------------------------------Cl= in group 7A=7O= in group 6A=6---------------------------------------------------------------Add +1 = because we have one (-) negative charge.
What element have the smallest atomic raduis in Group 7A?
Fluorine, as a halogen in Group 7A of the periodic table, has the smallest atomic radius due to its high effective nuclear charge and strong attraction for electrons. This makes the fluorine atom very compact with a small atomic radius compared to other elements in the same group.

What is the charge of ions on Astatine?
Astatine is in the group 7A of the periodic table. The members of this group all have an ionic charge of -1, so At (astatine) will have a -1 ionic charge.
What element have the smallest atomic raduis in Group 7A?
Fluorine, as a halogen in Group 7A of the periodic table, has the smallest atomic radius due to its high effective nuclear charge and strong attraction for electrons. This makes the fluorine atom very compact with a small atomic radius compared to other elements in the same group.
Are Group 7A elements the alkaline earth metals?
No, Group 7A elements are the halogens - a highly reactive group of nonmetals. Alkaline earth metals are found in Group 2A of the periodic table and are characterized by being shiny, silvery-white metals that react readily with water.
What is 7a in the periodic table?
"A" is not used as a symbol in the periodic table. Each element is represented by a unique symbol, such as "H" for hydrogen or "Na" for sodium. If you meant "7A" as a group number, group 7A includes the halogens (fluorine, chlorine, bromine, iodine, and astatine).
How does the electron configuration of an ion of a group 1A or group 7A element compare to that of the nearest noble gas?
What relationship exists between the electron structure of Group IA ion and the electron structure of the nearest Noble Gas?
What is 7a-a-a-a-a?
The expression ( 7a - a - a - a - a ) simplifies by combining like terms. You can group the ( a ) terms together: ( 7a - 4a ), which results in ( 3a ). Therefore, the simplified expression is ( 3a ).
When Group 7A elements in a periodic table form ions they lose or gain protons?
When Group 7A elements form ions, they gain an electron to achieve a stable electron configuration. This causes the atom to have a net negative charge since it now has one more electron than protons present in its nucleus.
What are the Group 1A and Group 7A elements examples of?
Sodium and Chlorine = Sodium Chloride Potassium and Iodine = Potassium Iodide
