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 …
WebTherefore, the group of magnesium is two. The valence electrons of all the elements in this group, including magnesium are two. Group-3 to 12 elements are called transition metals. The valence electrons of these elements vary by group. To determine the valence electrons of transition elements must know the electron configuration of that element.
Web2.Carbon is in Group 4A, so it has 4 valence electrons. 3.Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell.
