Within a horizontal row, mass of the elements increases as you go to the right. This is because as the atomic number increases, so does the number of protons and electrons.
This means that the total mass of the atom also increases because protons weigh approximately 1 Atomic Mass unit.
The rows (Horizontal) are called Periods and the Columms (Vertical) are called Groups.
The horizontal rows are named 'PERIODS'. The vertical columns are named 'GROUPS'.

It is called the Periodic Table of Elements.
They have similar chemical properties.
A horizontal row in the periodic table is called a period. There are seven periods in the periodic table, labeled from 1 to 7. Each period represents the energy levels of the elements within that row.
The statement applies to the horizontal rows or periods in the periodic table is that properties change going across each row.
The statement applies to the horizontal rows or periods in the Periodic Table is that properties change going across each row.
Yes. the horizontal rows on the periodic table are called periods.
They are the horizontal rows in the periodic table
A horizontal row on the periodic table of elements is called a period.
The horizontal rows are periods on periodic table. There are 7 horizontal rows in modern periodic table.
The horizontal rows are referred as periods. There are 7 periods in periodic table.
The horizontal sections of the periodic table are called periods.
Periods on the periodic table refer to the horizontal rows that categorize elements based on the number of electron shells they have. There are a total of 7 periods on the periodic table, each representing a different energy level for the elements within that row.
The horizontal rows of the periodic table are called Periods and the vertical rows are called groups.
The Horizontal row on the table is called a period
