The smaller size of cation (as Li+) and larger size of anion (as I-) is the main cause for the covalent character in ionic compound.

Is ammonia a ionic or covalent compound?

Ammonia is a covalent compound. It is a compound of two nonmetals, nitrogen and hydrogen, so the difference in electronegativity is not great enough to cause ionic bonding.


Is acetone an ionic or covalent compound?

No. The hydrogen in acetone only bonds with carbon, and not with the oxygen. In order to form hydrogen bonds a bond hydrogen must bond with with nitrogen, oxygen, or fluorine.


Is H2O covalent compound?

Yes. Water, or H2O, has covalent bonds.Related Information:Actually, they are polar covalent bonds. That means that the two hydrogen atoms form two covalent bonds with the one oxygen atom, causing it to be polar. This is because most of the electrons are pulled toward the hydrogen atoms, this will cause one end (Oxygen) of the molecule to be positively charged, and the other ends (Hydrogen) to be negatively charged. This is why water is known for it's hydrogen covalent bonds. That means that when one molecule of water is exposed to another molecule of water the negative ends of one are attracted to the positive end of the other (opposites attract). This polar attraction is what causes water have surface tension.


Which solute will cause a light bulb to glow brightly ch3oh or mgbr2?

MgBr2 will cause the bulb to glow brightly as it is an ionic compound and produces two ions per molecule . On the other hand, CH3OH is an organic compoound which is merely dissolved in water due to intermoleculer hydrogen bonding and is not a good electrolyte!


Why Pbcl2 is ionic and Pbcl4 is covalent?

apply fazan's rule, greater the charge on cation more is the polarising power and hence more covalent character polarising power of pb4+>pb2+ thus pbcl4 is more covalent than pbcl2 conversely pbcl2 more ionic than pbcl4

Is lithium nitride ionic or covalent?

Ionic, but with covaelnt character.. Lithium nitride is the only stable alkali metal nitride, it has an usual structure with 8 nitrogen atoms around each lithium ion. the small size of Li+ will cause significnt distortion of the electron cloud aroud the N3- ions leading to the "covalent" character.

What kind of compound that cause a person to sneeze?

Pepper, dust, and even cold air are compounds that can cause a person to sneeze. Any compound that irritates the lining of the nostrils can cause a sneeze.
