Covalent is a non-metal to a non-metal bond. See the answer. Metal hydrides are ionic, convalent or molecular in nature. 1. In KHCO3 there are two types of bonding going on. And PH3 is not ionic because Phosphorus is a non-metal and if H comes after something then it is also non-metal. 4. Electrolytes may be covalent compounds that chemically react with water to produce ions (for example, acids and bases), or they may be ionic compounds that dissociate to yield their constituent cations and anions, when dissolved. asked Mar 8, 2018 in Class XI Chemistry by rahul152 (-2,838 points) hydrogen. ionic - Sodium Chloride Covalent - Water ionic - Sodium Chloride Covalent - Water Is Na2CO3 ionic or covalent or both?

Khan Academy is a nonprofit with the mission of providing a free, world-class education for … Lattice energies calculated for ionic compounds are typically much higher than bond dissociation energies measured for covalent bonds. We differentiate between two types of compounds: IONIC and COVALENT. In a true covalent bond, the electronegativity values are the same (e.g., H 2, O 3), although in practice the electronegativity values just need to be close.If the electron is shared equally between the atoms forming a covalent bond, then … These compounds are held together by either ionic or covalent bonds. 1 answer.
