Answer:
B) valence electrons.
Explanation:
Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others. Thus, this property is typically used to determine the chemical properties of elements.
For example, oxygen has a total number of eight (8) electrons while neon has total number of ten (10) electrons. Therefore, an atom of oxygen is able to gain (receive) two (2) more electrons in order to have the same electron arrangements as the noble gas i.e an atom of neon with an atomic number of 10.
Basically, each free electrons (valence electrons) produces a covalent bond.
Hence, single, double, or triple covalent bonds in a carbon atom are formed from valence electrons.
Single, double, or triple covalent bonds in a carbon atom are formed from Valency electrons.
The valency electron are the electrons found in the outermost shell of an
atom.
The valency electron of an atom determines the kind of bonding that exist in
an element .
Neutral Carbon atoms has 6 electrons . The number of valency electrons
(electrons in the outermost shell) in Carbon is 4 valency electrons.
So, carbon can form covalent bond by sharing electrons with other atom of
an element. The bonding maybe single, double or triple bonds .
This bonding are formed by the electrons in the outermost shell(valency electrons)
