Eriq, a chemist, is running tests with four unknown elements. He has found that they all bond the same way, so he knows that they are in the same group on the periodic table of elements. The table shows other properties that Eriq observed.

The elements most likely are halogens because they usually display the same pattern of bonding as they are all diatomic molecules that need one electron to fill their outermost shell.

Another thing is that, halogens possess very strong type of ionic bonds which make them very reactive such that they react with metals to form salts. Due to this reason, they are called salt dormers.

There are other properties of these elements too such as: atomic radius, melting and boiling points, electronegativity e.t.c. They may increase or decrease down the group.

The elements belong to group 7A.

Answer:

Explanation:

The four elements are most likely halogens which belong to group 7A in the periodic table
