A good example of a negative ion is Chlorine minus (Cl-) which forms an ionic bond with Sodium plus (Na+), creating common table salt. Na+ + Cl- = NaCl
Ionic
The chemical formula of sodium chromate is Na2CrO4. The sodium cation is Na+ and the chromate anion is (CrO4)2-.
No
The first has a Positive (Na+) charge, the other has the same value but Negative (Cl-) charge in sodium chloride (NaCl, just as an example)
Sodium is Na; ionic compounds of sodium contain Na+

They have an ionic bond since Na is positively charged and Cl is negatively charged.its common salt
It's 1+ Yeah

No, it is not. Salt is an ionic compound made by a metal cation (Positively charge ion) and a non-metal anion (Negatively charged ion). There many types of salts like carbonates, chlorides, etc. An example for salt would be NaCl which is the common salt we use. This is a compound (an Ionic compound to be more specific) because, there are two elements which make up the substance. And Na (Sodium) has a positive charge and Cl (Chlorine) has a negative charge.
The first has a Positive (Na+) charge, the other has the same value but Negative (Cl-) charge in sodium chloride (NaCl, just as an example)
Yes. Sodium (Na+) has a 1+ charge while the sulfate (SO42-) has a 2- charge. That makes the molecule ionic. But because the sulfate ion (SO42-) is composed of 2 non-metals, S and O, that makes it a covalent bond. Therefore, it contains both ionic and covalent bonding.
The oxidation number is +1. (Oxidation number for an ion is the ionic charge)
