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 are all the groups called periodic table?

Group

  • Group 1: alkali metals, or lithium family.
  • Group 2: alkaline earth metals, or beryllium family.
  • Group 3: the scandium family.
  • Group 4: the titanium family.
  • Group 5: the vanadium family.
  • Group 6: the chromium family.
  • Group 7: the manganese family.
  • Group 8: the iron family.

What is group One known as on the periodic table?

alkali metal, any of the six chemical elements that make up Group 1 (Ia) of the periodic table—namely, lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). The alkali metals are so called because reaction with water forms alkalies (i.e., strong bases capable of neutralizing acids).

What is the other name of group one element?

Alkali Metals
Alkali metals are the chemical elements found in Group 1 of the periodic table. The alkali metals include: lithium, sodium, potassium, rubidium, cesium, and francium.

What are the 8 groups in periodic table?

The following are the 8 groups of the periodic table:

  • Alkali metals.
  • Alkaline earth metals.
  • Rare earth metals.
  • Crystallogens.
  • Pnictogens.
  • Chalcogens.
  • Halogens.
  • Noble gases.

What is another name for group 2?

alkaline earth metal
The other name for group 2 elements is alkaline earth metal. The elements are: Beryllium. Magnesium.

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.
