Answer:
I couldn't find options online for your question. But I can explain a little bit about it so you can identify the answer for yourself.
A binary ionic compound is made up of ions that have two different elements.
Of these two ions, one must be a metal and the other a nonmetallic.
The metallic atom will lose electrons, becoming a positive ion (cation), and the non-metallic atom will gain electrons, transforming into a negative ion (anion). Between them there is a very strong electrostatic attraction that is what holds them together.
Here are some examples of these types of compounds:
- Calcium hydroxide: Ca (OH) 2
