Which is the correct lewis structure for carbononitridic chloride (cncl)? a b c

Explanation:

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

In the Lewis-dot structure the valance electrons are shown by 'dot'.

In structure of carbononitridic chloride , chlorine atom is single bonded to carbon where as carbon is bonded by triple bond with nitrogen atom. It is a linear molecule.

Carbononitridic chloride (CNCl) = Cl-C≡N

The Lewis dot structure of carbononitridic chloride is given in an image.

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
