What is the left to right rows on the period table called?

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.


Which direction do periods go on the periodic table?

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.


As you move across a period of the periodic table from left to right what happens to the number of protons contained by each element?

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.


What is a period in the periodic table and how does it relate to the organization of elements?

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 .?

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.
