Question

what is the chemical formula write steps to write a chemical formula for ionic compounds​

Answer 1

Answer:

please mark it as brilliant

Explanation:

To find the formula of an ionic compound, first identify the cation and write down its symbol and charge. Then, identify the anion and write down its symbol and charge. Finally, combine the two ions to form an electrically neutral compound.

Answer 2

Chemical Formula:

A molecular chemical formula employs symbols to denote the molecule of an element or of a compound.

steps to write a chemical formula for ionic compounds:

• first identify the cation and write down its symbol and charge.
• identify the anion and write down its symbol and charge. Finally, combine the two ions to form an electrically neutral compound. In this video, we'll walk through this process for the ionic compound calcium bromide.
• Ionic compounds do not exist as molecules. In the solid state, ionic compounds are in crystal lattice containing many ions each of the cation and anion.
• An ionic formula, like NaCl , is an empirical formula. This formula merely indicates that sodium chloride is made of an equal number of sodium and chloride ions.
• Sodium sulfide, another ionic compound, has the formula Na2S .
• This formula indicates that this compound is made up of twice as many sodium ions as sulfide ions. This section will teach you how to find the correct ratio of ions, so that you can write a correct formula.

If you know the name of a binary ionic compound, you can write its chemical formula. Start by writing the metal ion with its charge, followed by the nonmetal ion with its charge. Because the overall compound must be electrically neutral, decide how many of each ion is needed in order for the positive and negative charge to cancel each other out.
