The chemical symbols for three different atoms or atomic cations with 27 electrons are

Explanation:

An atom is neutral specie with equal number of electrons and protons in it.

Atomic number =  Number of protons = Number of electrons

Atomic number =- Number electrons = 27

The atom with 27 atomic number Cobalt that Co.

A cation is an ionic species which carry positive charge.When an atom looses an electron it forms cation.

Copper has atomic number of 29. When the copper atom looses 2 electrons it get converted into copper cation that is with 27 electrons in its ion.

Nickel has atomic number of 28.When the nickel atom looses 1 electron it get converted into nickel cation that is with 27 electrons in its ion.

So,the chemical symbols for three different atoms or atomic cations with 27 electrons are

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements
