the number of valence electrons determine the reactivity of the atoms
Valence electrons are the electrons in the outermost shell. They are the electrons available for bonding and generally determine the number of bonds an atom can make
Valence electrons are the electrons in the outermost shell of an atom. These electrons are important in bonding and magnetism. For example, carbon has 4 valence electrons. It can make 4 covalent bonds to fulfill the octet rule. Also, if an atom has unpaired electrons, it is called paramagnetic and if an external magnetic field is applied, it will be attracted. If all of the electrons are paired, it is diamagnetic and will be repelled by an external magnetic field.
Valence electrons form the bonds between atoms in a molecule.
Elements on the periodic table in the same group have the same number of valence electrons. Since valence electrons are the only part of an atom that interacts with other atoms during a chemical reaction, you can make generalizations about elements' reactivity based upon what group they're in. Elements in the same group will behave similarly in chemical reactions even if they bear little resemblance to each other physically.
Noble gases have completely filled valence electrons. so removla of electrons will make them unstable
Carbon only has 4 valence electrons and so it can make all kinds of bonds. Carbon is a very important element on the planet if not the most important.
Mercury easily shares its valence electrons
Molecules or covalent compounds are formed by the sharing of valence electrons.
Valence electrons are the electrons in the outermost shell. They are the electrons available for bonding and generally determine the number of bonds an atom can make
These electrons are called "outershell electrons" or "valence electrons."

alkaline earth metals or group 2 elements have two valence electrons and make +2 ion.
They are on the outermost level of the electron shells. On the periodic table the valience electrons increase as they go over in groups. Valence electrons are located at the highest energy level present in an atom and they are almost responsible for its chemical properties. They are the electrons that participate in chemical reactions.
