A period 1 element is an element in the first period of the periodic table. The periodic table is arranged in rows to show repeating properties of the elements. When the atomic number increases, the element have different properties. A new row begins when chemical properties repeat. It means that elements in the same group have similar properties. The first period has less elements than any other periods in …

A period in the periodic table is a row of chemical elements. All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor. Arranged this way, groups of elements in the same column have similar chemical and physical properties, reflecting the periodic law. For example, the halogens lie in the second-last column and share similar properties, such as high reactivity and the tendency to gain one electron t
