Which element belongs to group 1 block 2?
The s-block in the periodic table of elements occupies the alkali metals and alkaline earth metals, also known as groups 1 and 2. Helium is also part of the s block. The principal quantum number “n” fills the s orbital. There is a maximum of two electrons that can occupy the s orbital.
What is the atomic structure for lithium?
A lithium atom is an atom of the chemical element lithium. Lithium is composed of three electrons bound by the electromagnetic force to a nucleus containing three protons along with either three or four neutrons, depending on the isotope, held together by the strong force.

Is Lithium a metal?
A highly reactive and inflammable element, lithium (Li) is the first alkali metal in the periodic table which consists of elements such as sodium (Na). Discovered in 1817 by the Swedish chemist Johan August Arfwedson, lithium is one of the three elements synthesized during the Big Bang along with hydrogen and helium.
Which element is in the same group as lithium?
The alkali metals are six chemical elements in Group 1, the leftmost column in the periodic table. They are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
Is lithium an element or compound?
lithium (Li), chemical element of Group 1 (Ia) in the periodic table, the alkali metal group, lightest of the solid elements. The metal itself—which is soft, white, and lustrous—and several of its alloys and compounds are produced on an industrial scale.
What element has an atomic number of 56?
Atomic Number 56. Atomic Number 56 is belong to element of Barium. Chemical symbol for Barium is Ba. Number of protons in Barium is 56. Atomic weight of Barium is 137.327 u or g/mol.
What is the periodic table of lithium?
Lithium – Periodic Table. Lithium is a 3. chemical element in the periodic table of elements. It has 3 protons and 3 electrons in the atomic structure. The chemical symbol for Lithium is Li.
How many protons are in the nucleus of a lithium atom?
Lithium is a chemical element with atomic number 3 which means there are 3 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs.
What is the electron configuration and density of lithium?
In the periodic table, the elements are listed in order of increasing atomic number Z. Electron configuration of Lithium is [He] 2s1. Possible oxidation states are +1. Density of Lithium is 0.535g/cm3. Typical densities of various substances are at atmospheric pressure.
