what are the horizontal rows on the periodic table called

by Terrill Towne Published 3 years ago Updated 2 years ago

The horizontal row of the periodic table is called the Period. The vertical row of the periodic table is called the Group. There are seven periods and eighteen groups in a modern periodic table.

How many vertical rows are there in periodic table?

  • The horizontal rows are called periods.
  • The vertical columns are called groups.
  • Elements in the same group are similar to each other.
  • The metals are on the left and the non-metals are on the right (hydrogen is a non-metal but is often put in the middle).

What are the names of the rows in the periodic table?

Reading Rows (Periods)

  • Number of elements. The first period only contains two, hydrogen (H) and helium (He). ...
  • Lanthanide and actinide series. The lanthanide and actinide series are usually presented as two separate rows beneath the main periodic table, and represent the inner transition metals.

What are the horizontal groupings in the periodic table named?

  • Lithium (Li)
  • Sodium (Na)
  • Potassium (K)
  • Rubidium (Rb)
  • Cesium (Cs)
  • Francium (Fr)

What do the rows mean on the periodic table?

What do periodic table rows mean? Each row represents one period; the period number of an element indicates how many of its energy levels house electrons. Sodium, for instance, sits in the third period, which means a sodium atom typically has electrons in the first three energy levels.

What does group 1 represent?

The columns are most straightforward to understand. For example, group 1 represent the alkali metals with all cations of 1+ in inorganic compounds and group 17 (IUPAC) represent the halogens with all 1- anions.

What are horizontal rows in the periodic table called?

Horizontal rows in periodic table are called periods , they are seven in numbers elements in same period may not have similar quality. while vertical rows in periodic table are called columns or family.

How does the periodic table order elements?

The periodic table describes the elements in their very atomic origin ordered by the number of protons in their nuclei (atomic number). The different neutron configurations that describe the isotopes per element are left out. Besides atomic number it orders elements according to electronic configuration to classify elements with similar chemical behavior. That can be in the form of columns or in the form of rows.

How many columns are there in the periodic table?

In periodic table elements are placed in seven rows and 18 columns. Rows are called periods and columns are called groups. In period 1, only two elements are placed, Hydrogen and Helium having atomic number, 1 and 2 respectively. This period is called very short period. In 2nd and 3rd periods Li (3) to Ne (10) and Na (11) to Ar (18) are placed. These are called short periods. In 4th and 5th periods K (19) to Kr (36) and Rb (37) to (Xe) 54 are present respectively. In 6th period Cs (55) to Rn (86) ...

How many groups are there in a row?

The rows (side to side) are called periods, in which there are 7. Likewise, the vertical columns (up and down) are called groups. There are 18 groups.

What happens at the end of the lithium row?

Add one more proton to helium, a gas, and you get lithium, a metal. At the end of lithium's row is neon, another gas. After neon comes sodium, a metal, and at the end of sodium's period another gas, argon.

What are columns called?

They are called periods. (The columns are called groups.)

Answer

If I'm not mistaken the horizontal rows are periods and the vertical columns are familes.

Answer

Each row of the periodic table is called a period and each column of the periodic table is called a group (or family). Some groups have specific names like the halogens or noble gases
