H2o is water.
h - hydrogen
o - oxygen
(H2) 2 atoms of hydrogen. (O) 1 atom of oxygen.
The "2" describes how many atoms of that substance there are - it shows that there are 2 hydrogen atoms. There is no "1" for o, or oxygen, because without a number, we automatically know that there is 1 atom, and not, say, six.
This may sound confusing, but it works out.
What else can I help you with?
Which element has the smallest number of proton in its atom?
The element with one proton per atom is hydrogen.
What is the simplest atom that contains one proton one electron and no neutrons?
The simplest atom that contains one proton, one electron, and no neutrons is the hydrogen atom.
The nucleus of a hydrogen atom is formed by?
The nucleus of a hydrogen atom is formed by a single proton.
How can there be 1 proton with a hydrogen atom with a mass?
Though a hydrogen atom typically has one proton, its mass is not solely determined by the proton. The mass of a hydrogen atom comes from the combination of the proton and an electron. The electron contributes a much smaller amount to the overall mass compared to the proton.
How is a hydrogen atom is different than a proton?
A hydrogen atom consists of a proton in its nucleus along with an electron orbiting around it. A proton is a subatomic particle found in the nucleus of an atom and carries a positive charge. In comparison, a hydrogen atom is a neutral particle since it has an equal number of protons and electrons.
Is hydrogen a compound or a mixture?
Hydrogen can be an atom (H1), a molecule (H2 or normal hydrogen), an isotope such as deuterium or tritium. Ionized Hydrogen is simply a proton.
What is an example for a proton?
Ionized hydrogen-1 isotope is identical to a proton.
What is an example for protons?
Ionized hydrogen-1 isotope is identical to a proton.
Which element has the smallest number of proton in its atom?
The element with one proton per atom is hydrogen.
How much bigger is a hydrogen atom than a proton?
A hydrogen atom is about 100,000 times larger in diameter compared to just a proton. This is because a hydrogen atom consists of a proton at its center with an electron cloud surrounding it, extending the size of the atom.
What is the simplest atom that contains one proton one electron and no neutrons?
The simplest atom that contains one proton, one electron, and no neutrons is the hydrogen atom.
What element has 1 proton in each atom?
Hydrogen has one proton in its nucleus.
The nucleus of a hydrogen atom is formed by?
The nucleus of a hydrogen atom is formed by a single proton.
What proton of an atom never changes in chemistry?
Hydrogen proton
Difference between hydrogen atom and a proton?
A hydrogen atom consists of a proton in its nucleus, along with an electron orbiting around it. A proton is a subatomic particle that is found in the nucleus of an atom and carries a positive charge. In other words, a hydrogen atom is a specific type of atom that contains a proton as one of its components.
You have 1 electron 1 proton and 1 neutron. What are you?
You are an atom of heavy hydrogen, or deuterium. Most hydrogen has one proton and one electron, which form a neutral atom. But once in a while, a neutron will stick to the proton, and then the atom, which is still hydrogen (it has just the one proton) will be about twice as massive as "regular" or "common" hydrogen. It is another isotope of hydrogen called heavy hydrogen or deuterium.
Number of protons in a hydrogen?
The "NUMBER" (#) of Protons in an Atom of Hydrogen is one (1). The number of protons is what makes a specific element that element. Hydrogen always has one proton no matter what. If someone says that a hydrogen atom has two protons(they are incorrect), it is no longer hydrogen; it is the element Helium.
