What are the similarities between the Group 7 elements?

What are the similarities between the Group 7 elements?

Elements in group seven have a number of similar properties, most importantly they have low melting and boiling points. This is of course a typical property of non-metals. From the lowest boiling and melting point to the highest, the group in order is fluorine, chlorine, bromine, iodine and astatine.

What does Group 7 on the periodic table have in common?

halogens
The Group 7 elements are called the halogens. They are placed in the vertical column, second from the right, in the periodic table . Chlorine, bromine and iodine are the three common Group 7 elements. Group 7 elements form salts when they react with metals.

What are the similarities between the halogens?

Halogens share many similar properties including: They all form acids when combined with hydrogen. They are all fairly toxic. They readily combine with metals to form salts.

Why do Group 7 elements all react in a similar way?

Atoms of group 7 elements all have seven electrons in their outer shell. This means that the halogens all have similar chemical reactions .

What is the difference between group1 and Group 7 on the periodic table?

As you go down group 1 (the alkali metals) in the periodic table, the elements get more reactive. As you go up group 7 (the halogens), again, the elements become more reactive.

Why do Group 1 and Group 7 elements react together?

Group 1 elements get more reactive down the group becasue with each step down the group the number of full electron rings increases by 1 and the outermost electron is further away from the positive nucleus.

Which are similarities in between the element of halogen group?

They all form acids when combined with hydrogen. They readily combine with metals to form salts. They have seven valence electrons in their outer shell. They all exist as diatomic molecules (two atoms ) when in their pure form.

Which of the following element shows similarity with the halogen group VIII?

Answer: Hydrogen shows similarity with alkali metals as well as halogens because of its electronic configuration , physical and chemical property.

Why do Group 1 and group 7 elements react together?
