The compound formed when hydrogen and chlorine combine is hydrogen chloride, with formula HCl. In pure form, this compound has highly polar covalent bonds, but when dissolved in water, the compound ionizes.
The ionic compound formed between magnesium and chlorine has the formula MgCl2.
The compound formed between rubidium and chlorine has the formula RbCl.
Under diffused sunlight, hydrogen gas and chlorine gas directly combine to form hydrogen chloride. Under direct sunlight the same reaction is explosive. It is not usually formed by its ions.
Hydrogen chloride. If you mix it with water, you get hydrochloric acid.
We can logically walk through this. Hydrogen has 1 proton, and 1 electron. Chlorine has 17. If these were to combine stably, Argon would be made. Argon is a noble gas and therefore has 8 full valence electron slots.
The compound is a salt, CaCl2 (calcium chloride), which is formed by ionic bonds.
When elements combine chemically compounds are formed. For instance, when hydrogen and oxygen gases chemically combine, water is formed. Note that if a molecule is made up of only one element, it is referred to as an element, not a compound.
HCl is a compound. It is formed by hydrogen and chlorine present in periodic table.
When two or more elements combine in chemistry, a compound is formed. Water is a compound made from oxygen and hydrogen. Salt is a compound. Vinegar is a compound.
There are no atoms of HCl in one molecule of HCl, because HCl is not an atom. It is a molecule. HCl is made of two parts: hydrogen atoms, and chlorine atoms. Each molecule of HCl contains one hydrogen atom and one chlorine atom. H stands for hydrogen, and Cl stands for chlorine. Compare this to H2O, which is the chemical formula for water. Water has 2 hydrogen atoms and 1 oxygen atom.
Hydrogen and carbon combine to form many, many different compounds known as hydrocarbons. Please see the link.
When they combine chemically, they form compounds, which can have very different chemical properties than the constituent elements.If they are combined physically, they only form mixtures, alloys, or colloids.
A compound
By the reaction of hydrogen and chlorine gas HCl (Hydrochloric acid) may be formed. To bring about this reaction free radicals of hydrogen and chlorine in the ionic form are needed.
The ionic compound formed between magnesium and chlorine has the formula MgCl2.
The compound formed between rubidium and chlorine has the formula RbCl.
When hydrogen burns, water is formed.
