Answer

Brief Explanations:

  1. In the periodic table, vertical columns are called groups or families.
  2. Horizontal rows are called periods.
  3. Elements in the same group have the same number of valence electrons, which gives them similar chemical properties.
  4. As you move from left - to - right across a period in the periodic table, the atomic number increases because the number of protons in the nucleus of the atoms increases.

Answer:

A vertical column of elements in the periodic table is called a group. A horizontal row of elements in the periodic table is called a period. Atoms of elements in the same group have the same number of valence electrons. As you move from left to right on the periodic table, the atomic number increases.
