What is the number of electrons needed for stability in the groups of the periodic table?
They r noble gases which have stable valance shell and grotp no. 18
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)
Which group contains eight valence electrons?
Group 18 contains eight valence electrons, namely the noble gases.
How man valence electrons does neon have?
Neon has 8 valence electrons. This is because neon is in the 8th group (or 18th column) of the periodic table, and elements in this group have a full set of 8 valence electrons.
Why are group A elements called Representative elements?
They follow a pattern for valence electrons.

What is the number of the family group with atoms that all ready have full valence shells?
The family is Group-18. They are noble elements.
Which group contains eight valence electrons?
Group 18 contains eight valence electrons, namely the noble gases.
What are the valence electron of an atom?
The valence electrons are found on the valence shell, the outermost shell of an atom. By using the periodic table and the group numbers, one can find the number of valence electrons for elements in groups (vertical columns) 1-2 and 13-18. For the 1st 2 groups (1 and 2), the group number tells the number of valence electrons for elements which belong in that group Elements in the 1st group have 1 valence electron and elements in the 2nd group have 2 valence electrons. For groups 13-18, refer to the tens' value (the teen value that is not the "1" in these cases). Elements in group 13 have 3 valence electrons, elements in group 14 have 4 and so on to the the final group, 18, where electrons have a full octet of valence electrons.
How man valence electrons does neon have?
Neon has 8 valence electrons. This is because neon is in the 8th group (or 18th column) of the periodic table, and elements in this group have a full set of 8 valence electrons.
Which group in the PTOE contains elements that hardly react?
Group 18, the noble gases, are elements that hardly react with other elements. This is because they have their full complement of eight valence electrons.
Why are group A elements called Representative elements?
They follow a pattern for valence electrons.
What is the number of valence electrons in group one?
Valence electrons are the electrons in the furthest electron shell from the nucleus.For the first three rows, essentially, the number of valence electrons is the number of squares the element is away from the beginning of the row at the left.For example. Sodium is the first (group 1) it has 1 valence electron. Magnesium is the second, it has 2 valence electrons.
Argon Noen Krypton and Xenon belong to the same...?
...group on the periodic table called the noble gases. These elements are characterized by their highly stable and unreactive nature due to having a full valence shell of electrons.
What do all elements in group 7 have in common?
All elements in group 7 of the periodic table, also known as the halogens, have 7 valence electrons. They are highly reactive nonmetals and readily form compounds with metals by gaining one electron to achieve a full valence shell. These elements include fluorine, chlorine, bromine, iodine, and astatine.
How can group members help us determine an atom's tendency with valence electrons?
Group members in the periodic table indicate the number of valence electrons an atom has, which directly influences its chemical behavior. Elements in the same group share similar properties because they have the same number of valence electrons, affecting their reactivity and bonding patterns. For example, group 1 elements have one valence electron and are highly reactive, while group 18 elements have a full set of valence electrons, making them largely inert. Understanding these group trends helps predict how an atom will interact with others based on its valence electron configuration.
