write 3 difference between hydrogen and halogens
While hydrogen is a single element with unique properties of its own, the halogens are a collection of elements.
1. Hydrogen and the halogens are all non-metallic elements, but they behave very differently. Hydrogen often combines with negative, non-metallic ions to form acids and organic molecules. Halogens, on the other hand, only form negatively-charged ions that react with metallic, positive ions to make ionic compounds like salts.
And its simplest natural state on Earth, hydrogen is a diatomic, molecular gas (H2). But halogen appears in all three states( solid liqiuid and gase)
2. One of the main underlying causes of the differences between hydrogen and the halogens is the size of the atoms involved. Hydrogen atoms are the smallest of all the elements, consisting of only one proton and one electron. Halogen atoms, in contrast, can be quite large.
3. Hydrogen gas is a combustible of inflammable gas. But halogens are not inflammable.
