A strong chemical bond is formed from the transfer or sharing of electrons between atomic centers and relies on the electrostatic attraction between the protons in nuclei and the electrons in the orbitals. The types of strong bond differ due to the difference in electronegativity of the constituent elements.
The name Nubia is of Egyptian origin. The meaning of Nubia is from Nubia Africa, gold. Nubia is generally used as a girl's name. It consists of 5 letters and 3 syllables and is pronounced Nu-bi-a.
