Identify the atom whose nucleus is composed of 56 protons and 82 neutrons
kkurt [141]
An atom is the smallest particle of an element that can take part in a chemical reaction. Its structure has a nucleus and energy levels. The nucleus of an atom contain protons and neutrons whereas the energy levels contain electrons.
For a particle containing 56 protons (atomic number) and 82 neutrons has 56 electrons since the number of protons and neutrons in an uncharged atom are equal.
The atom in this case is must be an isotope of Barium since barium has an atomic number of 56 .

Explanation:

                     Oxidation reactions are defined as,

In terms of Inorganic chemistry:

                 (i) <u>Removal of Electrons: </u>

                            Example:  Mg  →  Mg²⁺  +  2 e⁻

                (ii) <u>Addition of Oxygen:</u>

                            Example:  2 Mg  + O₂  →  2 MgO

In terms of Organic chemistry:

                (i) <u>Addition of Electrons: </u>

                            Example:  Cl₂  +  2 e⁻   →   2 Cl⁻

                (ii) <u>Addition of Hydrogen:</u>

                            Example:  H₂CCH₂  +  H₂    →   H₃CCH₃
