Halogens are highly reactive, and they can be harmful or lethal to biological organisms in sufficient quantities. This reactivity is due to highelectronegativity and high effective nuclear charge.
That depends on what you mean by harmful; any chemical can be harmful in the right (or wrong) situation. If not used or stored correctly, they can all damage property and cause serious injury - even death.
They share many properties, but one is that they all have 7 valence electrons.
Halogens are all non-metals, they are all very reactive, and they are all colorful.
Halogens are group seven on the Periodic Table, this means they take electrons during bonding as opposed to giving them. Halogens are often used for cleaning and disinfecting, most notably in pools. They are also poisonous and were introduced into warfare in the first world war. Halogens are common in acids such as hydro-CHLORIC acid.
One characteristic property of halogens is their high reactivity, especially when they react with metals to form salts. They also have a strong tendency to gain an electron to achieve a full outer shell, making them strong oxidizing agents. Additionally, halogens have distinct colors and can exist in various states of matter at room temperature, with their melting and boiling points increasing down the group in the periodic table.
Various chemicals can harm the ozone layer.The ones containing halogens are the most harmful.

A: 1. The halogens show a number of trends when moving down the group—for instance, decreasingelectronegativity and reactivity, and increasingmelting and boiling point. 2. Like other groups, the members of this family show patterns in its electron configuration, especially the outermost shells resulting in trends in chemical behavior.
Tornadoes are harmful in that they kill and injure people and damage and destroy crops and property. They are not beneficial.
Two main harmful effects of lightning strikes are loss of life and damage to property.
Yes they are - they are all toxic and corrosive.
Halogens are in Group 7
