What elements are 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 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 group B elements called?
transition metals
Group B elements are called transition metals.
What is Group 3/12 called?
the transition metals
The elements in groups 3-12 are called the transition metals.
What is Group 7 called?
The Group 7 elements are called the halogens. They are placed in the vertical column, second from the right, in the periodic table . Chlorine, bromine and iodine are the three common Group 7 elements. Group 7 elements form salts when they react with metals. The term ‘halogen’ means ‘salt former’.
What is Group 13 called?
Boron group element
Boron group element, any of the six chemical elements constituting Group 13 (IIIa) of the periodic table. The elements are boron (B), aluminum (Al), gallium (Ga), indium (In), thallium (Tl), and nihonium (Nh).
What is the deadliest element in the world?
Plutonium
Surely you know what Plutonium is. It’s one of the most dangerous, radioactive, toxic elements in the world. It’s used in atomic bombs and the production of nuclear energy.
What are groups 13 18 called?
representative elements
Groups 1, 2, and 13-18 are the representative elements (or main-group elements). Groups 3-12 are called the transition metals. The two rows at the bottom of the table are called inner transition metals.
