The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. Alkali metals group 1 of the periodic table are the alkali metals.

Families and periods periods in the periodic table.

Families of periodic table. Relatively low melting points decreasing with atomic mass. The halogen family consists of fluorine chlorine bromine iodine and astatine. Group 1a elements are the alkali metals and all have one electron in the outermost energy level because their electron configuration ends in s1.

Are located in the second column from the right side of the periodic table group 17. High thermal and electrical conductivity. Families in the periodic table.

All the members of a family of elements have the same number of valence electrons and similar chemical properties. Group 1 or ia. Low densities increasing with atomic mass.

They are highly reactive and do not occur freely in nature. The horizontal rows on the periodic table are called periods. Valence electrons and families.

An electron configuration shows the number. Halogens form ionic bonds with all kinds of elements. One common substance you see every day is sodium chloride nacl which is better known as salt.

Alkali metals or group 1 family of elements. Members of the families. The periodic table can be divided into nine families of elements each having similar properties.

They all have seven valence electrons which make them highly reactive for covalent bonds. Families in the periodic table are the vertical columns and are also referred to as groups.
