Bond formed by interactions between ions of opposite charges; NaCl - sodium chloride ethanol - C2H6O, hold atoms (or groups of atoms) together and create temporary connections that are essential to life, Weak chemical associations between partially negative O atoms and the partially positive H atoms of two water molecules, In water, the bond between the oxygen and the hydrogen is called a ___________bond, Bond formed when a partially positive hydrogen atom from one polar molecule is attracted to the partially negative atom in another molecule, True or false: Hydrogen bonds are formed between the hydrogen bond and oxygen atoms in a water molecule. ionic bond. [6][7] K2O is a basic oxide and reacts with water violently to produce the caustic potassium hydroxide. Ionic Bonds is shared under a CC BY-NC-SA 4.0 license and was authored, remixed, and/or curated by LibreTexts. It is a base. Potassium cannot be found free because it is too reactive. The set of pairs of elements whose atoms will combine to form a compound called ionic compound are:. Ionic compounds are formed when the number of electrons lost by one atom is equivalent to the number of electrons the other atom receives. 1 Answer. instead of sharing, there can be complete transfer of electrons from one atom to another.
