Is it true when elements chemically combined they form compounds that have properties that are similar to those of the uncombined elements?

Answer 1

Well, let's see . . .

-- Sodium is a poisonous, corrosive metal, that's a waxy solid at room temperature.

-- Chlorine is a poisonous halogen that's a gas at room temperature.

When sodium and chlorine chemically combine, they form sodium chloride,

which is table salt.

-- Hydrogen is a gas at room temperature, and forms an explosive mixture with air.

-- Oxygen is a gas at room temperature, we breathe it, and many thousands of

other substances will burn in it.

When hydrogen and oxygen chemically combine, they form dihydrogen oxide,

which is water.

Nope. Don't think so.

Answer 2

No, when elements chemically combine to form compounds, the properties of the compound are often very different from those of the uncombined elements. The combination of elements results in new chemical bonds and arrangements that give the compound unique properties that can be quite different from the properties of the individual elements.

Answer 3

No, the properties of the compounds do not mimic those of the constituent elements.

Answer 4

false

Answer 5

true
