What happens to the properties of elements when they are combined together to form a compound?

Answer 1

When different atoms join, a new substance is formed that has properties that differ from the properties of the original atoms. Example: Hydrogen and oxygen separately are colorless, odorless gases at room temperature. When combined in a chemical reaction, they form water.

Answer 2

When atoms form compounds the properties are often nothing like those of the individual elements. For example, salt is made of sodium and chlorine. Sodium is a shiny, soft, silvery metal that has a violent reaction to water. Chlorine is a poisonous greenish-yellow gas. These elements combine to form white table salt.

Answer 3

They may be completely lost when the elements are in a compound.

Here's an example:

-- Sodium is a corrosive, explosive, toxic, metal, with a waxy yellow surface.

-- Chlorine is a poisonous green gas.

-- When sodium and chlorine join and form a compound, the compound is called

'sodium chloride' . . . ordinary white non-toxic table salt.

Answer 4

The chemical properties of the elements are usually drastically changed. However, some nuclear properties such as radioactivity and the frequency of spectral lines that correspond to ejection of electrons from non-valence shells of the atoms can remain unchanged.

Answer 5

The atoms lose their individual properties and gain the properties of the compound.

Answer 6

whats the answer that's what im asking!!!!!!!!!

It is four hydrogen atoms and one carbon atom to form methane (CH4)

Answer 7

The compound formed often has properties that aren't anything like those of the individual elements but it sucks

Answer 8

The compound will have different properties than the individual atoms of which it is composed.

Answer 9

All the chemical and physical properties are modified.
