What is the mass of an atomic nucleus?
The hydrogen-1 nucleus is the same as the mass of a proton - since it is a proton. The proton's mass is 1.67×10−27 kg. Other nuclei have several times this mass - up to about 250 times the mass of a hydrogen nucleus.
What is the mass and volume of the nucleus?
The nucleus is a very small part of an atom, containing nearly all of its mass in a tiny volume. The mass of a nucleus depends on the number of protons and neutrons it contains, while its volume is estimated to be about 1 femtometer cubed, which is extremely small.
Does a hydrogen atom have a neutron in its nucleus?
No, a hydrogen atom does not have a neutron in its nucleus. A hydrogen atom consists of only one proton in its nucleus.
Where can the most mass be found in an atom?
Essentially all of the atom's mass is in the nucleus. In the lightest atom, that of hydrogen, it's about 99.95 percent. In the heaviest naturally occurring atom, that of Uranium238, it's about 99.979 percent.
What is the fraction of the hydrogen atom's mass that is in the nucleus?
The precise figure varies from element to element and isotope to isotope depending on the number of neutrons in the nucleus, however it is always at least 99.95% which is the ratio between an electron and a proton.
Can hydrogen have three neutrons in its nucleus?
No, because the mass of hydrogen is only one.
who particle has greatest mass electron proton neutron or hydrogen nucleus?
hydrgen nucleus
What is the mass number of hydrogen?
The mass number of the most common hydrogen isotope, Hydrogen-1, is one
What you hydrogens mass number?
Hydrogen is a non metal element. Atomic mass of it is 1.
What is the mass of an atomic nucleus?
The hydrogen-1 nucleus is the same as the mass of a proton - since it is a proton. The proton's mass is 1.67×10−27 kg. Other nuclei have several times this mass - up to about 250 times the mass of a hydrogen nucleus.
What is the atomic number and atomic mass for hydrogen?
Each isotope of each element has an atomic mass number. The atomic mass numbers for hydrogen are 1, 2 and 3. That's because hydrogen has three isotopes. "Regular" hydrogen has a single proton in its nucleus. It's atomic mass is 1. There is also heavy hydrogen, which has a neutron bound to the proton in its nucleus. It's atomic mass is 2. Heavy heavy hydrogen has two neutrons bound together with the proton. It's atomic mass is 3. A link is provided to the Wikipedia article on hydrogen.
How does the mass of the nucleus compared to mass of an electron?
The mass of a nucleus varies according to the atomic number (ie according to what element it is). For hydrogen , the simplest nucleus, the combined mass of the one proton and the one neutron would be equal in mass to 3672 electrons.
How does the mass of the nucleus compared to the mass of electrons?
The mass of a nucleus varies according to the atomic number (ie according to what element it is). For hydrogen , the simplest nucleus, the combined mass of the one proton and the one neutron would be equal in mass to 3672 electrons.
What is the mass number in hydrogen?
Hydrogen is a non metal element. Mass number of it is1.
A nucleon has the least mass in the nucleus of uranium iron plutonium hydrogen?
The masses of the nucleons are independent from the type of nucleus.
Which atom has an average mass not equal to its common isotope?
Hydrogen atom has an average mass not equal to its common isotope. The most common isotope of hydrogen, hydrogen-1, does not have a neutron in its nucleus, while the average mass of a hydrogen atom accounts for the other isotopes of hydrogen which do contain neutrons.
What is the mass number of a neutron and a proton in hydrogen?
The mass number of a neutron is 1, as it contains one unit of mass. The mass number of a proton is also 1, as it contains one unit of mass. In hydrogen, the nucleus usually consists of one proton, so the mass number of a proton in hydrogen is 1.
