What is the name of group number 1?

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 group A and B in periodic table?

Elements are arranged by reactivity in the periodic table. … The columns with B (IB through VIIIB) are called the transition elements. The columns with A (IA through VIIIA) are called the main group elements. The elements can also be divided into two main groups, the metals and the non-metals.

What is Group 13 on the periodic table called?

What is the name of group 3 12 on the periodic table?

All the elements in groups 3–12 are transition metals. Transition metals include the elements that are placed below the periodic table. Those that follow lanthanum (La) are called lanthanides. They are all shiny, relatively reactive metals.

Why is it called Group 8?

Group 8 elements are also known as the noble gasses. These elements already have a full valence shell with 8 valence electrons. This leaves the elements non-reactive as they are already stable and in a low energy state.

Why do we call Group 0 Group 0?

Why is it called group 0? All noble gases are colourless, odourless and unreactive. Because noble gases are so unreactive, there are few patterns, or trends, among the group. This makes them difficult to isolate and identify.
