Question

using the periodic table predict the whether of the following chloride ionic or convert. SiCl4,PCl3, CaCl2, CsCl, CuCl2, and CrCl3?​

Answer 1

Answer: a.
`SiCl_4` : covalent

b.
`PCl_3` : covalent

c.
`CaCl_2` : ionic

d.
`CsCl`: ionic

e.
`CuCl` : ionic

f.
`CrCl_3` : ionic

Step-by-step explanation:

A covalent bond is formed when an element shares its valence electron with another element. This bond is formed between two non metals.

An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element or the metal and the element which accepts the electrons is known as electronegative element or non metal.

a.
`SiCl_4` contain covalent bonds as they are made up of non metals only.

b.
`PCl_3` contain covalent bonds as they are made up of non metals only.

c.
`CaCl_2` contain ionic bonds as it is formed between a metal and a non metal.

d.
`CsCl` contain contain ionic bonds as it is formed between a metal and a non metal.

e.
`CuCl` contain contain ionic bonds as it is formed between a metal and a non metal.

f.
`CrCl_3` contain contain ionic bonds as it is formed between a metal and a non metal.
