The horizontal rows are referred as periods. There are 7 periods in Periodic Table.
The horizontal rows on the periodic table are called periods.
Horizontal rows of elements in the periodic table are called periods. Each period represents a different energy level, with elements in the same period having the same number of electron shells. Periods are arranged in numerical order from left to right on the periodic table.
Periods on the periodic table are the horizontal rows that go from left to right.
Periods on the periodic table are the horizontal rows running from left to right. There are 7 periods in total on the periodic table. Each period represents the principle energy level of the elements.
the horizontal rows are called periods the vertical columns are called groups A periodic table is a tabular display of the chemical elements, organized on the basis of their atomic numbers, electron configurations, and recurring chemical properties. Elements are presented in order of increasing atomic number.
There seems to be a typo in your question. If you meant a "horizontal row" (left to right) of the periodic table, those are called periods. If you meant a "vertical column" (up and down) of the periodic table, those are called groups.
The horizontal rows on the periodic table are called periods.
Horizontal rows of elements in the periodic table are called periods. Each period represents a different energy level, with elements in the same period having the same number of electron shells. Periods are arranged in numerical order from left to right on the periodic table.
Horizontal rows on the periodic table are called periods. Each period represents the number of energy levels or electron shells that an atom's valence electrons occupy. Moving from left to right across a period, the number of protons and electrons increases.
The horizontal rows on the Periodic Chart are called Periods.The vertical columns on the are called Groups, or sometimes Families.
Horizontal rows of elements in the periodic table are called periods. In a period, the number of protons and electrons increases by one as you move from left to right.
The horizontal rows on the periodic table are called periods. There are 7 periods in total, each representing a different energy level or shell of electrons in an atom. Moving from left to right across a period, the number of protons and electrons increases, resulting in an increase in atomic number.
Periods on the periodic table are the horizontal rows that go from left to right.
The seven horizontal rows of the periodic table are called periods. They are related by the increasing number of protons in the nucleus of the atoms as you move from left to right across a period. This results in a gradual change in the chemical properties of the elements within a period.
Periods on the periodic table are the horizontal rows running from left to right. There are 7 periods in total on the periodic table. Each period represents the principle energy level of the elements.
The seven horizontal rows of the periodic table are called "periods". They are numbered from 1 to 7, with each period representing the energy level or shell in which the elements in that row have their outermost electrons. As you move from left to right across a period, the number of protons in an element's nucleus increases, resulting in a gradual change in properties.
A triangle has three sides. The two sides that are perpendicular are called legs and the diagonal side is called the hypotenuse. Whichever side is horizontal (usually one of the legs) is also called the base.
