How many bonds can calcium form
WebThe attraction between oppositely charged ions is called an. ionic bond. , and it is one of the main types of chemical bonds in chemistry. Ionic bonds are caused by electrons transferring from one atom to another. In electron transfer, the number of electrons lost must equal the number of electrons gained. We saw this in the formation of NaCl. WebThis comes in handy especially when drawing Lewis structures. It’s called the HONC rule, or sometimes known as HONC 1234 rule.
