what are the names of the columns in the periodic table?
97623
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.
1450751
Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. ... They are the electrons involved in chemical bonds with other elements. Every element in the first column (group one) has one electron in its outer shell.
977783
The periodic table is divided into four blocks (s, p, d, f) based on which sublevel is in the process of being filled. Alkali metals, alkaline earth metals, halogens, and noble gases are the common names of groups 1, 2, 17, and 18.
1459178
The periodic table is organized in periods (rows from left to right) and groups (columns from top to bottom) by increasing atomic number. According to periodic law, elements with similar chemical and physical properties are in the same group. This is because they have the same valence shell electron configuration.
1470120
The periodic table on the left separates elements into three groups: the metals (green in the table), nonmetals (orange), and metalloids (blue). Most elements are metals.
1296521
The periodic table also has a special name for its vertical columns. Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements.

The Periodic Table: Families and Periods. In the periodic table of elements, there are seven horizontal rows of elements called periods. The vertical columns of elements are called groups, or families. The most common way the periodic table is classified by metals, nonmetals, and metalloids.
1069000
The modern periodic table is used to organize all the known elements. Elements are arranged in the table by increasing atomic number. In the modern periodic table, each element is represented by its chemical symbol. ... Columns of the periodic table are called groups. Elements in the same group have similar properties.
991848
The d-block elements are found in groups 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 of the periodic table; d-block elements are also known as the transition metals. The d orbital is filled with the electronic shell “n-1.”
1190206
The elements are arranged in seven horizontal rows, called periods or series, and 18 vertical columns, called groups. Groups are labeled at the top of each column. In the United States, the labels traditionally were numerals with capital letters.
844916
Why is the periodic table called the periodic table? It is called the periodic table because of the way the elements are arranged. You'll notice they're in rows and columns.
873579
There are four main groups of elements in the periodic table: main group metals, non-metals, metalloids, and transition metals (See types of elements).
760213
The structure of the table shows periodic trends. The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. The columns, called groups, contain elements with similar chemical behaviours.
244955
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. ... The horizontal rows on the periodic table are called periods.
354594
The periodic table brings order to information about the chemical elements. ... The chemical elements are arranged in order of increasing atomic number. The horizontal rows are called periods and the vertical columns are called groups. Elements in the same group have similar chemical properties.
932603
All elements in the first column of the Periodic Table have 1 valence electron in an s orbital. These elements are known as Group 1A metals or alkali metals. All elements in the second column of the Periodic Table have 2 valence electrons in an s orbital.

The periodic table is a tabular array of the chemical elements organized by atomic number, from the element with the lowest atomic number, hydrogen, to the element with the highest atomic number, oganesson. The atomic number of an element is the number of protons in the nucleus of an atom of that element.
