It is because only certain (the outer) electrons are available for chemical bonding that they are called valence electrons. By definition, the electrons available for bonding are called valence electrons. The others are more tightly bound to the nucleus.
Yes, valence electrons are the only electrons involved in bonding. This is so because the other orbitals are all ready stable.
If Electrons were involved in bonding between atoms they would become positively charged.
yes its true, because electron , is taken as subtraction, so we have it as e- so that it can be able to magnet
For the main group elements, yes. The transition elements often use additional electrons besides just the valence electrons when forming chemical bonds.
Valence electrons
Either lose 5 electrons, which is least likely, or gain 3 electrons.
It would belong to group XVI, the group with oxygen.
If an element has less than four valence electrons, it will tend to lose its valence electrons and form cations. If an element has more than four valence electrons, it will tend to gain electrons and form anions. An element that has four valence electrons will tend to form covalent bonds rather than ionic bonds.
An atom that has fewer than 8 valence electrons is more reactive, or more likely to form bonds, than an atom with 8 valence electron. Atoms bond by gaining, losing, or sharing electrons in order to have a filled outermost energy level with 8 valence electrons.
It has a lone pair of valence electrons.
Ionic
The importance of valence electrons is that atoms in the same group ("groups" in the periodic table are the vertical columns- for example, nickel and platinum are in the tenth column; therefore, in the same group). Atoms of elements in the same group have the same number of valence electrons, so they have similar properties. Hope that helped with your homework! ;D
It indicates how many electrons are required to complete a full valence shell.
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
Either lose 5 electrons, which is least likely, or gain 3 electrons.
The Valence electrons, i.e. those in the outer shell of a compound are most likely to be involved in bonding. This is because they are further away from the nucleus of their atom, so experience less attractive force towards it. They are also shielded from this attraction by any electrons between them and the nucleus. Therefore, they require less energy to remove.

The valence electrons of the element are very shielded. The valence electrons are far from the nucleus.
Electrons called valence electrons are most likely removed. These are the outermost energy level electrons.
