How is the mass number of a atom indicated?
The mass number is the sum of protons and neutrons in the nucleus of an atom.
How many protons are in a carbom atom?
An atom's atomic number gives us its number of protons. Carbon's atomic number is 6. Thus, it has 6 protons.
If the atomic mass of an atom is 48 and the atom contains 20 protons how many neutrons does the atom contain?
If the atomic mass of the atom is 48 and it contains 20 protons, then the atom contains 28 neutrons. This can be calculated by subtracting the number of protons from the atomic mass, since the atomic mass includes both protons and neutrons.
How can an atom be electrically neutral when its protons change?
Generally an atom contains similar number of electrons and protons. That is why an atom is neutral.
How many protons and neutrons are in atom of 160 Gd?
An atom of (^{160}\text{Gd}) (Gadolinium) has 64 protons, as indicated by its atomic number. To find the number of neutrons, subtract the atomic number from the mass number: (160 - 64 = 96) neutrons. Therefore, (^{160}\text{Gd}) contains 64 protons and 96 neutrons.
How many protons does C have in it?
An atom's atomic number gives its number of protons. Carbon's atomic number is 6. Thus, carbon contains 6 protons per atom.
How many electrons are in a neutral atom of 130 56 ba?
Any neutral atom of barium contains 56 electrons, the counter charge for the 56 protons contained in the nucleus of a barium atom, as indicated by its atomic number, 56.
What has six protons?
C atom contains 6 protons. Atomic number is six.
How many protons does one atom of element Sodium?
The atomic number of an element gives its number of protons per atom. Sodium's atomic number is 11. Thus, sodium has 11 protons per atom.
What is the mass number of an atom that contains?
nucleons
What indicates the number of an electron in a neutral atom?
The number of an electron in a neutral atom is indicated by the atomic number, which is equal to the number of protons in the nucleus of the atom. In a neutral atom, the number of electrons is the same as the number of protons.
How many protons and electrons are contained in an atom of element ruthenium?
An atom of ruthenium contains 44 protons and 44 electrons. This is because the number of protons in an atom determines its identity, and for a neutral atom, the number of protons equals the number of electrons.
