Halogens are rarely found in native state because halogens are highly reactive.
<h3>
What is Halogens ?</h3>
The group 17 elements are known as Halogen group. These elements include Fluorine, Chlorine, Bromine, Iodine and Astatine. Halogens react with metals to form salts. Halogens are non metals. Halogens are highly reactive and halogens are never found in pure form. Halogens not occur in free state.
<h3>How many valence electron are present in Halogens ?</h3>
Halogens have seven valence electrons in the outermost shell. The electronic configuration of Halogen is ns² np⁵.
Thus from the above conclusion we can say that Halogens are rarely found in native state because halogens are highly reactive.

Answer:
3.0 atm is correct
Explanation:
303,900 pa = 2.999259 atm
303,900 pa = 2279.4371 mmHg
<span>These two opposite ions attract each other and form the ionic bond. Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds.</span>
