number
The number of protons in an atom of an element is its atomic number. It determines the element's identity and is unique for each element. The number of protons also defines the element's chemical properties.
the number of protons in an element is called the atomic number and there is no way to see how many electrons an element has.
the answer is that it is called a atomic number.
The number of protons of a chemical element is equal with atomic number.
The number of protons in an element is called the atomic number.
Different isotopes of the same element have different numbers of neutrons but the same number of protons. The sum of the protons and neutrons is called the mass number. If you know the mass number and the number of protons (which is the atomic number), then you simply subtract the protons (or atomic number) from the mass number and the result is the number of neutrons. Example: Carbon-14 has a mass number of 14. Carbon's atomic number (and number of protons) is 6. So, 14 - 6 = 8 neutrons.
The number of protons in an atom is called the atomic number. It determines the element's identity and its place on the periodic table.
The atomic number, or Z, is the number of protons in the nucleus of an atom of an element. This is what determines what element an atom is. A link can be found below.
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.
The mass number is the sum of protons and neutrons in the atomic nucleus. The number of protons is equal to the atomic number.
The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus. In this case, the element has 4 protons and 5 neutrons, so its atomic mass is 4 + 5 = 9 atomic mass units (amu). The number of electrons does not affect the atomic mass.
It is called the atomic number.
