What is the name for the columns in the periodic table?

What is the name for the columns in the periodic table?

The elements are arranged in seven horizontal rows, called periods or series, and 18 vertical columns, called groups.

What are the columns up and down of a periodic table called?

The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.

What do the columns on a periodic table mean?

groups
The columns of the table represent groups, or families, of elements. The elements in a group often look and behave similarly, because they have the same number of electrons in their outermost shell — the face they show to the world.

What is the first column of the periodic table called?

Alkali Metals
Alkali Metals: Facts About the Elements on the First Column of the Periodic Table. There are alkali metals all around you right now. Sodium is found in table salt, lithium in your phone battery and potassium in your bananas. Alkali metals make up six different elements found in the first column of the periodic table.

What are the 4 groups of the periodic table?

Definitions of groups, periods, alkali metals, alkaline earth metals, halogens, and noble gases. How metals, non-metals, and metalloids can be identified by the position on the periodic table.

What are groups and columns in the periodic table?

Groups and periods are two ways of categorizing elements in the periodic table. Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period.

What is the second column of the periodic table?

alkaline earth metals
The second column of elements from the left of the periodic table is known as the Group 2 or alkaline earth metals. It consists of beryllium, magnesium, calcium, strontium, barium, and radium.

What are the elements of the periodic table?

The elements present in the periodic table are classified under different groups, depending on their chemical and physical properties. They are, metalloids, alkali metals, alkaline earth metals, transition metals, other elements, non-metals, halogens, noble gases and rare earth elements.

What is the modern periodic table?

Modern Periodic Table, also known as the Periodic Table , is a tabular arrangement in which chemical elements are arranged according to their atomic numbers, configuration of electrons and chemical properties. A Modern Periodic Table consists of four block, i.e., the “S”, “P”, “D” and “F” blocks.

What does periodic table mean?

Periodic Table. A table in which the chemical elements are arranged in order of increasing atomic number. Elements with similar properties are arranged in the same column (called a group), and elements with the same number of electron shells are arranged in the same row (called a period).
