So for the families labeled with a Roman numeral and an A, the Roman numeral gives the number of valence electrons.

\r\nThe Roman numeral makes it very easy to determine that oxygen (O) has six valence electrons (its in the VIA family), that silicon (Si) has four, and so on. It depends on the particular shell being considered. Groups 312 are in the middle of the periodic table and are the transition elements, listed as B in older tables. How many electrons can be accommodated in the za subshell? By clicking Accept All, you consent to the use of ALL the cookies. Each period corresponds to the successive occupation of the orbitals in a valence shell of the atom, with the long periods corresponding to the occupation of the orbitals of a d subshell. Fluorine (F), chlorine (Cl), bromine (Br), and iodine (I) also exhibit similar properties to each other, but these properties are drastically different from those of any of the elements above. Group of elements that may have properties of metals and nonmetals, or somewhere in between. The vertical columns of elements are called groups, or families. In Figure $\PageIndex{1}$, selenium lies above and to the right of the diagonal line marking the boundary between metals and nonmetals, so it should be a nonmetal. The number of the columns, which chemists call Groups is the number of valence electrons. the same electronic shell. As you move down the table, every row adds an orbital. We also use third-party cookies that help us analyze and understand how you use this website. Most solid nonmetals are brittle, so they break into small pieces when hit with a hammer or pulled into a wire. Note, however, that because selenium is close to the metal-nonmetal dividing line, it would not be surprising if selenium were similar to a semimetal in some of its properties. It does not store any personal data. These electron configurations show that there are some similarities among each group of elements in terms of their .\r\n

Keep this in mind about the number of valence electrons and the Roman numeral column number: the IA family has 1 valence electron; the IIA family has 2 valence electrons; the VIIA family has 7 valence electrons; and the VIIIA family has 8 valence electrons.
