It immediately combines with oxygen to form water.<\/strong><\/p>\n<p>Hydrogen is the most abundant element in the universe, but it is not found in large quantities in the Earth&#8217;s atmosphere. This is because hydrogen is highly reactive and will quickly combine with oxygen to form water. The Earth&#8217;s atmosphere is composed mostly of nitrogen (78%), oxygen (21%), and argon (1%). The remaining 1% is made up of trace gases, including hydrogen.<\/p>\n<p>Hydrogen is a colorless, odorless, and tasteless gas. It is the lightest element in the universe and has the lowest density of any gas. Hydrogen is also highly flammable and can be explosive when mixed with air.<\/p>\n<p>The Earth&#8217;s atmosphere is constantly being replenished with hydrogen from the sun.
