Group-17 in the Periodic Table gains electron most readily. The elements in this group require only one electron to complete its octet.
Metals give electrons.
The Alkali Metals, which are the elements in Group 1 of the periodic table, each have one lone electron in their valence shell. And each of these elements wants to get rid of that single electron. These metals, which include lithium, sodium, potassium, rubidium, caesium and francium, are the most likely to lose electrons.
Silicon. Magnesium and sodium are metals and readily lose electrons to form cations, Mg2+ and Na+. Fluorine readily gains an electron to form the anion F-. Silicon on the otherhand in group 14 would need to gain 4 or lose 4 electrons to achieve the octet.
The alkaline earth group has two valence electrons.
The elements in group 2 lose 2 electrons to create an ion.
elements of group 17 (most readily) followed by group 16 and group 15
Group 16 elements.
A Group 6A element gains two electrons A Group 2A element loses two electrons A Group 3A element loses three electrons A Group 3A element loses three electrons group 1a element loses one electron group 7a gains one electron
Group 13 has an oxidation number of 3+ so it is more likely to lose electrons than gain them, but it is possible that it gains them
Since Selenium is a Chalcogen (meaning it's in group 6A on the Periodic Table), it gains 2 electrons to form an ion with a charge of -2.
all the members of 3rd A group of periodic table have 3 electrons in outermost shell they are B ,Al, Ga, Tl and In.
The groups of electrons with 7 valence electrons are groups 7 and 17 on the periodic table.
Group VII A or XVII or Halogens.
Metals give electrons.
