How many valence electrons does carbon have?A) oneB) twoC) threeD) fourE) five

The number of valence electrons in an atom governs its bonding behavior. Therefore elements whose atoms can have the same number of valence electrons are grouped together in the periodic table of the elements.. The most reactive kind of metallic element is an alkali metal of group 1 (e.g. sodium or potassium); this is because such an atom has only a single valence electron; during the …

Description. The combining capacity or affinity of an atom of a given element is determined by the number of hydrogen atoms that it combines with. In methane carbon has a valence of 4; in ammonia nitrogen has a valence of 3; in water oxygen has a valence of 2; and in hydrogen chloride chlorine has a valence of 1.Chlorine as it has a valence of one can be substituted for hydrogen.

The octet rule is a chemical rule of thumb that reflects the theory that main group elements tend to bond in such a way that each atom has eight electrons in its valence shell giving it the same electronic configuration as a noble gas.The rule is especially applicable to carbon nitrogen oxygen and the halogens but also to metals such as sodium or magnesium.

In chemistry and atomic physics an electron shell may be thought of as an orbit followed by electrons around an atom’s nucleus.The closest shell to the nucleus is called the “1 shell” (also called the “K shell”) followed by the “2 shell” (or “L shell”) then the “3 shell” (or “M shell”) and so on farther and farther from the nucleus.The shells correspond to the principal quantum numbers (n …

A molecular orbital diagram or MO diagram is a qualitative descriptive tool explaining chemical bonding in molecules in terms of molecular orbital theory in general and the linear combination of atomic orbitals (LCAO) method in particular. A …
