Isotopes are atomic elements with the same proton number. The atomic number of the Ru atom in the periodic table will be 44 and the mass will be 100.9.
<h3>What are atomic numbers and mass?</h3>
Atomic numbers are the number of protons present in the nucleus of the atom. Whereas the atomic mass is the total number of protons and the neutrons of the atom.
The atomic number is the number of protons and remains constant for the same element at different places or planets. Hence, the atomic number of Ruthenium will be 44.
The atomic mass depends on the relative abundance and is calculated as:
Therefore, the atomic mass of Ru is 100.9 and the atomic number is 44.

Explanation:
Answer:
Explanation:
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion. Both atoms are joint together by electrostatic interaction and ionic compound sodium chloride is formed.
Covalent bond:
It is formed by the sharing of electron pair between bonded atoms.
The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive.
For example:
In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive and both bonded atoms connected together through covalent bond.
