Question

Define element and compound with two three example of each

Answer 1

A chemical compound is a chemical substance that is made of two or more atoms of different elements that share a chemical bond. A chemical formula represents the ratio of atoms per element that make up the chemical compound. This is done via the use of subscripts. The subscript that lies to the right of the symbol for each element indicates the number of atoms of that element that make up that chemical compound.

Examples of chemical compounds are as follows:

- Water (H2O, consisting of 2 hydrogen atoms and one oxygen atom)

- Carbon dioxide (CO2, consisting of one carbon atom and two oxygen atoms)

- Sodium Chloride (NaCl, consisting of one sodium atom and one chloride atom)

- Methane (CH4, consisting of one carbon atom and four hydrogen atoms)

The second link provided below show a slue of other examples of chemical compounds.

Answer 2

Answer:

ELEMENTS : an element is a pure substance which cannot be broken down by chemical means, consisting of atoms which have identical numbers of protons in their atomic nuclei. The number of protons in the nucleus is the defining property of an element, and is referred to as the atomic number. ...Carbon, oxygen, hydrogen, gold, silver and iron are examples of elements.

COMPOUND: Chemical compound, any substance composed of identical molecules consisting of atoms of two or more chemical elements.....Water, carbon dioxide and table salt are some examples of compounds
