A zero vector, also known as a null vector, is a vector that has an arbitrary direction and has no magnitude. When a vector is added to a zero... View Article
The elements that belong to group 18 of the modern periodic table can be considered as some of the best electric insulators since they all... View Article
No, diamonds do not conduct electricity. Due to the tetrahedral arrangement of covalently bonded carbon atoms in diamonds, there are no free... View Article
The energy needed to detach an electron from an atom in its gas phase is determined by ionisation energy. The energy for ionisation reduces as we... View Article
A shorter bond length implies a stronger bond in general. Atoms that are closer together are more closely bound to each other and there is a weak... View Article
NaCl is an ionic compound whereas CuCl is a covalent compound. A common ionic compound is sodium chloride (NaCl). Sodium in its outermost shell... View Article
Ionization energies are always positive and the amount of energy needed to detach an electron from an isolated gaseous atom is the ionisation... View Article
The best reducing metal is lithium, with the maximum negative value of electrode potential. By convention, reduction potential, or the propensity... View Article
Potassium is not an Alkaline Earth Metal it is Alkali metal. Potassium (K), Group 1 (Ia) chemical element of the periodic table, group of alkali... View Article
Except for beryllium, all alkaline earth metals often react with water to form highly alkaline hydroxides, which should be treated with great... View Article
Ever since antiquity, alkali metal compounds have been identified. In 1807, by electrolytically preparing (and naming) potassium and sodium... View Article
Water is a weak field ligand. The electronegative O atom is extremely electron-withdrawing, so the electron pair on O and a metal d-orbital have... View Article
Bond polarity in chemistry is the division of electric charge around a bond, leading to an electric dipole or dipole moment for a molecule or its... View Article
