The "valence" electrons are responsible for chemical reactions and bonding. Valence electrons are found in the outer most orbital of the atom, farthest away from the nucleus.
Because in nature the elements seek to either give out electrons of take electrons. So the elements that gives out electrons bonds with the elements that takes electrons so that both of them are "happy"
Valence electrons, the are on the outermost layer of the atom
valence electrons or electrons of the last level of electrons in an atom or the electrons in the last energy level of an atom, they have a negative chargethese electrons usually are the ones that take part in reacting, such as ionic bonding and covalent bonding :)
When an atom undergoes chemical change, only the outermost (valence electrons) are involved.
Valence electrons, which are electrons in the outermost energy level of an atom, are involved in bonding with other atoms. These electrons are responsible for forming chemical bonds by either sharing, gaining, or losing electrons to achieve a stable configuration.
The external electron shell is responsible for the formation of chemical bonds.
Electrons
The valence electrons are the only electrons involved in chemical bonding. In covalent bonding sharing occurs In ionic bonding electrons are tranferrred In metallic bonding they are deloclaised across the lattice
Calcium has the same number of electrons available for bonding as magnesium. Both elements have 2 electrons available for bonding in the outer shell.

Metals and nonmetals tend to undergo ionic bonding when reacting with one another. Metals lose electrons and become positively charged ions, and the nonmetals gain these electrons and become negatively charged ions. The electrostatic attraction between the oppositely charged ions forms the ionic bond.
number of electrons in the bonding shell vary according to the element. for example group 1 in the periodic table contains elements with ony one electron in their bonding shell, similarly group 2 has elements with two electrons in its bonding shell and so on. the group number in the periodic table denotes the number of electrons in the bonding shell of each element present in that particular group
Valence Electrons are the outermost electrons in an element and they are used for bonding with other elements.
Four bond types:Covalent: pairs of electrons are shared roughly equally between two elements.Polar: pairs of electrons are shared between two elements, but pulled much closer to one element.Ionic: electrons pulled from one element by another element creating attraction by charge.Metallic: electrons "dance" across multiple elements in order to satisfy the requirements of all deficient elements.
