What does 3B mean on the periodic table?

Group 3B (3) In most periodic tables, lanthanum and actinium are considered to be a part of Group 3B, but in others lanthanum and actinium are considered part of the inner transition elements, leaving lutetium and lawrencium in Group 3B instead.

What is 1A on the periodic table?

The Alkali Metals 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 1A 3B and 7A examples on the periodic table groups?

In the periodic table, there are 7 horizontal rows of elements are known as period and 18 vertical columns of elements are known as group. Hence, 1A, 3B, and 7A are examples of group number on the periodic table.

What is 7A in periodic table?

Group 7A (or VIIA) of the periodic table are the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). The name "halogen" means "salt former", derived from the Greek words halo- ("salt") and -gen ("formation").

What does group 7A of the periodic table contain?

Group 7A (or VIIA) of the periodic table are the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).

What element is in group 1 period 7?

Francium is a highly radioactive metal that decays into astatine, radium, and radon. As an alkali metal, it has one valence electron. Francium was discovered by Marguerite Perey in France (from which the element takes its name) in 1939.

What are the 7 families of the periodic table?

These families are alkali metals, alkaline earth metals, transition metals, post-transition metals, metalloids, halogens, noble metals, and noble gases. Many of these families belong to a single group on the periodic table. However, not all of the families overlap with periodic table groups.

What are Group 7A elements?

Group 7A (or VIIA) of the periodic table are the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).

What is 1a/2A periodic table?

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). They are harder and less reactive than the alkali metals of Group 1A….Group 2A — The Alkaline Earth Metals.

Where is group 7A on the periodic table?

Fluorine is a halogen, which is a group of non-metals located on the right side of the periodic table that includes fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). Most halogens are electron-hungry, like fluorine. Halogens can also be referred to as group 7A, group 17, or group VIIA elements.
