What is a group in a periodic table?
group, in chemistry, a column in the periodic table of the chemical elements. In a group, the chemical elements have atoms with identical valence electron counts and identical valence vacancy counts. To learn an element’s name, atomic number, electron configuration, atomic weight, and more, select one from the table.
What is the other name for the group I elements?
The elements in group IA are called the alkali metals.
What is Group 1 on the periodic table called?

What is the name of Group 7 on the periodic table?
Group 7 Elements Also called the halogens.
What is Group 3 called on the periodic table?
Transition Metals
The elements from Group 3 to 12 are called Transition Metals. They include the Scandium, Titanium, Vanadium, Chromium, Manganese, Iron, Cobalt, Nickel, Copper, and Zinc families of elements. Transition Metals are hard and dense, are good conductors of heat and electricity, and can be bent easily.
What is Group 2 called?
Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). In most cases, the alkaline earth metals are ionized to form a 2+ charge.

What are the groups on the periodic table called?
Summary. 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 are the characteristics of the periodic table?
The characteristics of modern periodic table are: The arrangement of elements in modern periodic table is based on their electronic configurations. The horizontal rows of elements in periodic table are called periods. There are 7 periods in modern periodic table. The elements in a period have consecutive atomic numbers.
What are the columns on periodic table of elements called?
Key Takeaways: Parts of the Periodic Table The periodic table orders elements by increasing atomic number, which is the number of protons in the atom of an element. The rows of the periodic table are called periods. The columns of the periodic table are called groups. The three broad categories of elements are metals, nonmetals, and metalloids.
What is periodic table?
The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends.
