Which of the following halogens has the weakest attraction for electrons?
Leokris [45]

Answer:

I

Explanation:

Among the halogens given in this problem, iodine has the lowest attraction for electrons.

This property is known as electronegativity.

Electronegativity is expressed as the relative tendency with which the atoms of the element attracts valence electrons in a chemical bond.

  • As you go down the periodic group the electronegativity decreases.
  • The most electronegative element on the periodic table is fluorine.
  • Down the group, iodine is the least electronegative
  • This is due to the large size of its atom.

Some versions of the periodic table show hydrogen at the top of Group 1A(1) and at the top of Group 7A(17). What properties of h
lawyer [7]

Answer:Hydrogen is placed such because it exhibits some similar characteristics of both group1 and group VII elements.

Explanation:

The reason why hydrogen is similar to group 1 metals:

#It has same valence electron and inorder achieve octet state it can lose that electron and forms H+ ion

#It acts as a good reducing agent similar to group1 metals

#It can also halides

Similarity to halogens:

#hydrogen can also gain one electron to gain noble gas configuration. It can combine with other non metals to form molecules with covalent bonding.

#It exists as diatomin molecule,H2

#Have the same electronegativity nature

#its reaction with other metal
