What is The ratio of atoms in HCI is

Each molecule of HCl is composed of a one-to-one ratio of hydrogen and chlorine.

Explanation:

At room temperature, HCl is a colorless, poisonous gas. Dissolve it in water, and, voilà, you have hydrochloric acid. For the record, acids are substances that release hydrogen ions in water. The more hydrogen ions an acid releases in water, the stronger the acid (see "What is an ion?" below). If you concluded from the above discussion that HCl releases many hydrogen ions in water, you are right!

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
