What is The atomic mass of an element is equal to?
The number of protons, electrons, and neutrons:P
What is atomic mass of an atom equal to?
The atomic mass of an element is equal to the number of protons.
Why is the mass number bigger than the atomic number?
The atomic number of an element is the number of protonsin its atom's nucleus. The mass number of an element is the number of nucleons (protons or neutrons) in its atom's nucleus. Except in the case of hydrogen, which has no neutrons, the mass number will always be higher.
The mass number of an elements is equal to?
the total number of protons and neutrons in the nucleus.
What is mass number of an isotope?
The mass number of an element is equal to the number of protons in the nucleus, and this always determines the element in the Periodic Table. Different isotopes of the same element have differing numbers of neutrons in the nucleus, but always the same number of protons.
What is the atomic mass the same as?
The Atomic Mass is equal to the number of protons and electrons that an element has.
What is The atomic mass of an element is equal to?
The number of protons, electrons, and neutrons:P
What is atomic mass of an atom equal to?
The atomic mass of an element is equal to the number of protons.
The molar mass of an element is equal to?
The element's average atomic mass.
Why is the mass number bigger than the atomic number?
The atomic number of an element is the number of protonsin its atom's nucleus. The mass number of an element is the number of nucleons (protons or neutrons) in its atom's nucleus. Except in the case of hydrogen, which has no neutrons, the mass number will always be higher.
What is the mass number of an atom equal to?
The mass number of an atom is equal to the number of protons and neutrons that are in the nucleus of the atom. Atoms are the basic units of a chemical element.
Does the mass number equal the same number of electrons?
The atomic mass number does not equal the number of electrons in the element. The atomic number, on the other hand, does usually equal the number of electrons in the element, With the exception of ions.
How is the mass number related to the number of protons and neutrons and atoms has?
The mass number of an element is equal to the number of protons plus the number of neutrons.
The mass number of an elements is equal to?
the total number of protons and neutrons in the nucleus.
How do you calculate protons and neutrons?
If you think to the number of protons in an element atom this number is equal to atomic number of this element. The calculation of the mass of the proton and other properties are another questions and problems.
Is the atomic mass equal to the molar mass?
1. The molecular mass of a compound is the sum oh the atomic weights of the elements contained in the molecule of this compound. 2. The atomic number of an element is the number of this element in the Periodic Table of Mendeleev; the atomic number is equal to number of protons and electrons.
What best describe an element has atomic number equal to 6 and mass number equal to 12?
This is the cabon isotope 612C.
