What are the groups of elements on the periodic table called?

What are the groups of elements on the periodic table called?

Groups are numbered 1–18 from left to right. The elements in group 1 are known as the alkali metals; those in group 2 are the alkaline earth metals; those in 15 are the pnictogens; those in 16 are the chalcogens; those in 17 are the halogens; and those in 18 are the noble gases.

What are the elements in the second group called?

alkaline-earth metal, any of the six chemical elements that comprise Group 2 (IIa) of the periodic table. The elements are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

What is the group name for Group 1?

Alkali Metals
Group 1: Alkali Metals This group includes the elements Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium. Alkali metals are very reactive.

What are the following groups known as Group 1?

Group 1 is known as the alkali metals.

What are group 3 elements called?

Group 3A (or IIIA) of the periodic table includes the metalloid boron (B), as well as the metals aluminum (Al), gallium (Ga), indium (In), and thallium (Tl). Boron forms mostly covalent bonds, while the other elements in Group 3A form mostly ionic bonds.

What are the elements in the first group that are extremely reactive called?

Group 1: Alkali Metals – These metals are extremely reactive. They all have 1 valence electron (same as the group #).

What are the group of elements?

In group 1 of the periodic table, all the elements except hydrogen (H) are alkali metals.

  • Group 2: Alkaline Earth Metals. The alkaline Earth metals include all the elements in group 2 (see Figure below).
  • Groups 3-12: Transition Metals.
  • Groups 13-16: Groups Containing Metalloids.
  • Group 17: Halogens.
  • Group 18: Noble Gases.

How many elements are there in periodic table?

118 elements
At present, 118 elements are known to us. All these have different properties. Out of these 118, only 94 are naturally occurring. As different elements were being discovered, scientists gathered more and more information about the properties of these elements.

What is Group 1 called?

The Group 1 elements in the periodic table are known as the alkali metals. They include lithium, sodium and potassium, which all react vigorously with water to produce an alkaline solution.

What elements are in Group A?

Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). These are (except for hydrogen) soft, shiny, low-melting, highly reactive metals, which tarnish when exposed to air.

What are Group 4 elements called?

titanium group
Group 4 is the second group of transition metals in the periodic table. It contains the four elements titanium (Ti), zirconium (Zr), hafnium (Hf), and rutherfordium (Rf). The group is also called the titanium group or titanium family after its lightest member.

How many groups are in the periodic table?

Groups are numbered from 1 to 18. From left to right in the periodic table, there are two groups (1 and 2) of elements in the s-block, or hydrogen block, of the periodic table; ten groups (3 through 12) in the d-block, or transition block; and six groups (13 through 18) in the p-block, or main block.
