Answer 2

I hope mera answer se aapka solutions hi jaaye,✌️✌️✌️The bonds in these diatomic molecules are non-polar covalent single bonds. However, halogensreadily combine with most elements and are never seen uncombined in nature. As a general rule, fluorine is the most reactive halogen and astatine isthe least reactive. All halogens form Group 1 salts with similar properties
