Which of the following substances are held together by an ionic bond? (SELECT ALL THAT APPLY)ResponsesMnMnBPBPHBrHBrCSe2CSe 2C6H12O6C 6 H 12 O 6Ca3P2Ca 3 P 2TaAt4

Ionic bonds are formed between a metal and a non-metal. They involve the transfer of electrons from the metal atom to the non-metal atom.

Looking at the options:

1. MnMn: This is not an ionic bond. It's a metallic bond between two manganese atoms.

2. BP: This is not an ionic bond. It's a covalent bond between boron and phosphorus.

3. HBr: This is not an ionic bond. It's a covalent bond between hydrogen and bromine.

4. CSe2: This is not an ionic bond. It's a covalent bond between carbon and selenium.

5. C6H12O6: This is not an ionic bond. It's a covalent bond between carbon, hydrogen, and oxygen.

6. Ca3P2: This is an ionic bond. It's formed between calcium (a metal) and phosphorus (a non-metal).

7. TaAt4: This is not an ionic bond. It's a covalent bond between tantalum and astatine.

So, the only substance held together by an ionic bond in the given options is Ca3P2.
