All periods begin with an alkali metal, excepting the first which begin with hydrogen..
The left to right rows on the periodic table are called periods. Each period represents the energy levels of the elements, with the elements in the same period having the same number of electron shells.
In the periodic table of the elements, a period is a horizontal row of the table. Elements in the same period have the same number of energy levels.
The number of protons contained by each element increases by one as you move across a period of the periodic table from left to right. This is because each element in a period has one more proton in its nucleus than the element before it.
A period in the periodic table is a horizontal row of elements that share similar chemical properties. Each period represents the number of electron shells in an atom. The organization of elements into periods helps to show trends in properties as you move across the table from left to right.
Each period in the periodic table corresponds to the number of electron shells an element's atoms possess. As you move from left to right across a period, the number of protons increases gradually, resulting in a corresponding increase in the number of electron shells.
Reactivity of metals decreases from left to right in the specific period of theperiodic table.

Cations are mainly found on the left side of the period table.
Each period in the periodic table corresponds to the number of electron shells an element's atoms possess. As you move from left to right across a period, the number of protons increases gradually, resulting in a corresponding increase in the number of electron shells.
Period 6 has the most metals out of all periods on the periodic table.
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
