25 WORDS – HYDROGEN
Hydrogen, H, is a highly flammable gas (H2)and the most common
component of the universe. It is the lightest element ever and is colorless,
odorless, and tasteless. It's also in most organic compounds. Hydrogen, H,
is orderless, colorless, tasteless, and nonmetallic element with the atomic 1, and
it's also roughly 75% of the universe's mass. It's also the most abundant
chemical element on the periodic table.
Hydrogen(H) is a gas, and is the first element on the periodic
table. It lacks color, taste, or odor, and is highly flammable.
Its molecular formula is H2.
Hydrogen (symbolized H) is one of the elements. Its atomic number is 1 and it is
a colorless, tasteless, odorless nonmetallic gas. Hydrogen is highly flammable
and is the lightest of all the elements.
Hydrogen, or H2, is an elemental gas present in a trace amount in earths
atmosphere. Hydrogen is somewhat reactive because of its flammability. It is
used as a component in fertilizer and fossil fuels.
Hydrogen, H, atomic number one, is the lightest element. Hydrogen makes
up about 75 percent of the universe's elemental mass. H2, its diatomic
gas, is used to upgrade fossil fuels and make ammonia. Hydrogen: Hydrogen,
H2, is an elemental gas with an atomic mass of 1.00794. This diatomic molecule is the
lightest and most abundant element in the universe. It is also colorless, odorless, and
highly flammable.
Hydrogen; Hydrogen, H2, is the most abundant element in the universe. Pure
hydrogen is not easily found on Earth, but is extracted from hydrocarbons such
as methane via industrial processes.
Hydrogen, H, is the lightest element found on the periodic table of elements. At room
temperature, hydrogen is colorless, odorless, and tasteless. Hydrogen is most abundant, making
up approx. 75% of the universes mass.
Hydrogen is the first element on the periodic table, with an average atomic mass of 1.00794. It is
the most abundant element in the universe, and it is contained in many organic compounds,
particularly hydrocarbons.
Hydrogen, most abundant in the universe, is the chemical element
with atomic number 1, and an atomic mass of 1.00794 amu, the
lightest of all known elements. It exists as a diatomic gas (H2).
Hydrogen is the most abundant gas in the universe. It along with helium make
up most of the sun, it also has a lot to do with solar flares and the explosion of
stars. It is the atomic number one and has the atomic mass 1.000794.
Hydrogen is a colorless, nonmetallic, and highly flammable
gas. Stars in the main sequence are mainly composed of
