As we know that 1amu not equal to mass of 1 proton then why protium is equal to 1amu?
The Atomic Mass unit (amu) is defined as 1/12 the mass of a carbon-12 atom. It is a unit of mass that is used to describe the masses of atoms and molecules. The mass of a proton is actually slightly less than the mass of a carbon-12 atom, so it is not equal to 1 amu. However, the mass of a protium atom (which is an atom that consists of a single proton and no neutrons) is very close to 1 amu. This is because the mass of the proton makes up most of the mass of a protium atom. Therefore, protium is often said to be "approximately equal" to 1 amu.

How many isotopes of hydrogen are know?
There are three known naturally occurring isotopes of hydrogen; hydrogen-1 with one proton and no neutrons, hydrogen-2 with one proton and one neutron, and hydrogen-3 with one proton and two neutrons.
How many neutrons and protrons does americium have?
Americium has an atomic symbol of Am. Looking at a periodic table, you'll see that it has an atomic number of 95. This indicates the number of protons. As for neutrons: Again referring back to the periodic table, you'll notice Am has an atomic mass of 243amu. Each proton is 1amu, and we know Am has 95 of those. Also, every neutron is 1amu. So, we get 243amu - 95amu = 148amu. And thus there are 148 neutrons.
A proton is a subatomic particle carrying a charge equal to but opposite that of an electron true or false?
True. But please note that there are other differences between the proton and the electron as well - for example, the proton has a larger mass, and the proton is made up of smaller particles, while the electron - as far as we know - is not.
How do you know the charge of a proton?
By definition, a proton is positive, so a proton will always have a positive charge.
Can you find an element if you only know the number of electrons in a neutral atom?
Yes. In a neutral atom, the +ve and -ve charges will be equal. Electrons are negatively charged, and protons have an equal and opposite positive charge. Therefore the proton number will equal the electron number. Elements are classified by their Atomic number, and this equals the proton number. So if you had a neutral atom with 6 elements, you know it has 6 protons in the nucleus and an atomic number of 6 - Carbon.
Does nuclei of all atoms contain both protons and neutrons?
no the proton and the neutron are in a atom if there are so many protons it will over power the neutron if there are to many neutrons it will over power the proton neutrons and protons must be equal for the atom to be stable.
How many protons does the element F have?
H is Hydrogen, and Hydrogen has 1 proton. Also, remember to always use correct capitalization in the periodic table. If you don't, it's often impossible to know what you're talking about. For instance, Sc is not the same as SC.
Is proton an ionized hydrogen atom?
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.
Is only one kind of atom in a element?
Yes and no. All elements are composed of the same basic "stuff"--- protons, neutrons and electrons. But when the number of protons, neutrons and electrons change, a completely different element appears. A given element will always have the same number of protons but can have several numbers of neutrons. Substances with identical numbers of protons but different numbers of neutrons are called isotopes. Take for example hydrogen. One proton bound in an atom with no neutrons is what we know as protium, the most abundant isotope of hydrogen. One proton bound in an atom with one neutron is called deuterium while one proton bound in an atom with two neutrons is called tritium. These are all isotopes of hydrogen because they contain only one proton, but differ in the their number of neutrons.
How do we know if two atoms of the same element?
The number of protons.
How do isotopes hydrogen 2 and hydrogen 3 differ?
Hydrogen isotopes. 1) Protium (H-1) has 1 proton and one electron 2)Deuterium (H-2) Has one proton, one electron and 1 neutron. 3)Tritium (H-3) has 1 proton, one electron and 2 neutrons
Which has a greater mass an electron or a proton?
In kilograms, an electron's mass is ~9 x 10^(-31). A proton's mass is ~1.7 x 10^(-27). The mass of the proton is more than 1000 times of an electron.
