They are the same! Elements in group IA (alkali metals) have 1 valence electrons. Elements in group IIA (alkaline earth metals) have 2 valence electrons. Group IIIA (boron family) has 3 valence electrons, and so on.

The electron dot structure shows the valence electrons on the atom.


There is no relationship between this, however most of the elements in a group have the same number of valence electrons.


Group number shows number of elecconce in valence shell.


Halogen family members, or elements in group 17, have 7 valence electrons.


Valence electrons are the electrons on the outer shell of an atom.


Titanium has the valence electron configuration of [Ar] 3d2 4s2. This means that Ti has 2 valence electrons, lying in the 4th s orbital. Note the relationship between the d-orbital and valence electrons is more complicated, but they are not regularly considered valence electrons.


All of the members of the carbon family have 4 valence electrons.


Non metal can have 5,6,7 valence electrons. They are members of group-15,16,17.


Elements in the same group have the same number of valence electrons.



It shows similarities because it deals only with VALENCE electrons, and all members of the same group have the same number of valence electrons.


When valence electrons are wholly transferred between two atoms, an ionic bond forms. If the valence electrons are shared, it is a covalent bond.



The number of valent electrons an atom has, predicts its ablility to form bonds.


the force of attraction between then nucleus and the valence electrons is less than that between the nucleus and the core electrons


Valence electrons are electrons on the outermost shell/orbitals. Sheilding electrons are inner electrons that block valence electrons from protons causing less attraction.


Valence electrons, those electrons in the outer shell of atoms, have lower ionization energies than inner electrons have. It doesn't take as much energy to remove valence electrons from a given atom as it does to remove electrons from closer-in orbitals.


Electrons involved in bonding between atoms are valence electrons.


In a covalent bond electrons are shared between two electrons.


The more to the right of the periodic table the more reactive Only for nonmetals, for metals the most reactive are to the left and have 1 valence electron. Nonmetals have many, 6 or 7, valence electrons that make them very reactive.


Silicon, the most widely used semiconductor, has four valence electrons. This places it in between the conductive metals, which have one to three valence electrons, and the non-conductive non-metals which have five to eight valence electrons.


Less valence electrons (1 to 3) in the outermost shell of an atom usually means a good conductor. (silver, cooper, gold). 5 t0 8 valence electrons are found in glass, rubber, ceramic, plastic, non-conductors.


Valence electrons are shared between molecules


The valence shell is an atom's outer shell of electrons that is involved in chemical bonding. A valence electron is one of the electrons in that shell.


A carbon atom has 4 valence electrons. I am not sure what you mean by C2; do you mean two carbon atoms? If so, they have 8 valence electrons between them.
