How many electrons must a chlorine atom gain to complete its octet?
A chlorine atom must gain one electron to complete its octet, as it has 7 electrons in its outer shell and needs 8 to achieve a stable electron configuration.
How many electrons must be gained or lost for calcium to attain a noble-gas electron configuration?
Calcium's electron configuration is [Ar] 4s2. To attain a noble gas configuration, calcium must lose 2 electrons to have the same electron configuration as argon, 4s2 3d10.
How many electrons does the group 7A need to gain?
Group 7A elements (also known as Group 17) typically need to gain one electron to achieve a stable octet configuration in their outer shell. This allows them to reach a stable electron configuration similar to the noble gases.
How many electrons must be gained or lost for a sulfide ion to achieve a noble gas electron configuration?
A sulfide ion (S2-) must gain two electrons to achieve a noble gas electron configuration, similar to that of a stable, inert gas such as argon. This transfer allows the sulfide ion to fill its valence shell with eight electrons, satisfying the octet rule.
In order for an atom to become an ion it must due what?
An atom becomes an ion by gaining or losing electrons. If it gains electrons, it becomes a negatively charged ion called an anion. If it loses electrons, it becomes a positively charged ion called a cation.
How many electrons must be gained or lost for selenium to achieve a noble gas electron configuration?
Selenium should gain two electrons and lose six electrons to achieve a noble gas electron configuration.
How many electrons must be gained or lost for Iodine to achieve a noble gas electron configuration?
Iodine, located in Group 17 of the periodic table, has 7 valence electrons. To achieve a noble gas electron configuration (like Xenon), it must gain 1 electron to fill its valence shell and attain stability.

Potassium has one electron in its outer shell. It will lose this electron to achieve the noble gas electron configuration of argon in its previous full shell.
How many electrons does the group 7A need to gain?
Group 7A elements (also known as Group 17) typically need to gain one electron to achieve a stable octet configuration in their outer shell. This allows them to reach a stable electron configuration similar to the noble gases.
How many electrons must a halogen gain to reach stability?
Halogens are in the seventh group on the periodic table, and thus have seven electrons in their outer shell. In order to attain a noble gas configuration, it must gain an electron to form an octet, which is when eight electrons are in the outer shell.
