Is h2so4 a polyatomic ion?
Polyatomic Ionic Compound SulfuricAcid

How is a compound ionic?
Ionic compounds are compounds made up ofions. These ions are atoms that gain or loseelectrons, giving them a net positive or negative charge.Ions of opposite charge are held together by very strongionic bonds within the compound. These bonds form aunique crystal lattice structure, making them difficult tobreak.
How do you recognize an ionic compound?
Compounds containing two elements (so called binarycompounds) can either have ionic or covalent bonding.
- If a compound is made from a metal and a non-metal, its bondingwill be ionic.
- If a compound is made from two non-metals, its bonding will becovalent.
What is the formula of phosphide?
Its chemical formula is sometimesP3–. It does not always have thatformula. It is a reducing agent. Phosphides (chemicalcompounds having the phosphide ion in them) react with acidsto make phosphine gas. Sodium phosphide is anexample.
What is potassium phosphite?
Potassium phosphite is a soil applied materialthat has recently gained attention as a method for improving plantvigor and health. Various products containing potassiumphosphite are sold as either fertilizers to addresspotassium deficiencies, or as fungicide products to managespecific disease issues.
How do you name ionic compounds?
An ionic compound is named first by its cationand then by its anion. The cation has the same name as itselement. For example, K+1 is called thepotassium ion, just as K is called the potassium atom. The anion isnamed by taking the elemental name, removing the ending, andadding “ide.”
What is the symbol for the ion with 19 protons and 18 electrons?

Does Na2CO3 have ionic and covalent bonds?
Sodium Carbonate, Na2CO3, is an ioniccompound that contains covalent bonds within the carbonateanion. Ionic and covalent are *types* of bonds, notproperties of a molecule as a whole.
What type of bond is NaHCO3?
Storage and Disposal. There is an ionic bondbetween the Na+ and the HCO3 in a crystal lattice. Theintermolecular bonds are weaker than the intramolecularbonds because the covalent bonds in theintramolecular forces are the strongest type ofbond.
Why is sugar a covalent bond?
Sugars contain covalent bonds. This isbecause all the covalent bonds in sugar moleculesarise as a result of electron sharing between theatoms.
