FAKE TAN TIP 1: SCRUB UP. âExfoliate, exfoliate exfoliate! This will remove dead skin cells and create a smooth and uniform surface on the skin for the tan to be applied to, which will in turn result in an even golden colour.
Covalent chemical bonds involve the sharing of a pair of valence electrons by two atoms, in contrast to the transfer of electrons in ionic bonds. Such bonds lead to stable molecules if they share electrons in such a way as to create a noble gas configuration for each atom. Hydrogen gas forms the simplest covalent bond in the diatomic hydrogen molecule. The halogens such as chlorine also exist as diatomic gases by forming covalent bonds.
About Covalent and Ionic Bonds. The covalent bond is formed when two atoms are able to share electrons whereas the ionic bond is formed when the sharing is so unequal that an electron from atom A is completely lost to atom B, resulting in a pair of ions. Each atom consists of protons, neutrons and electrons.
