How many electrons will Magnesium lose to have the same electron configuration has Neon?
Magnesium will lose 2 electrons to have the same electron configuration as Neon. Neon has a full valence shell with 8 electrons, and Magnesium has 2 valence electrons. By losing 2 electrons, Magnesium can achieve a full valence shell and the same electron configuration as Neon.

Boron has 3 valence electrons.Boron has 3 valence electrons.
What does the group number of a element tell about valence electrons?
All elements in the same A group will have the same number of valence electrons.
How many valence electrons are in the element fluorine and do the same for chlorine and bromine?

Atoms of element that are in the same group have the same number of?
valence electrons
What element as the same number of valence electrons as As?
Silicon is the element. It is present in same group as C.
What do Valence Electrons determine?
Valence electrons determine the reactivity and chemical behavior of an element. Elements with the same number of valence electrons exhibit similar properties and tend to form similar types of chemical bonds.
What is the same for every element in the same period?

Which element has the same number of valence electrons as As (arsenic)?
Sb (antimony)
which element has the same number of valence electrons as As(arsenic)?
Sb (antimony)
How can i look at the periodic table and tell how many valence electrons an element has?
The group of the element indicates the amount of valence electrons. For example, the alkali metals have one valence electron and is in group one whilst the halogens have seven valence electrons and are in group seven.
