The number of protons in the nucleus of an atom of this element will determine its atomic number. Only this.
If the atom is not charged (in other words, not an ion), this is the same as the number of electrons in the atom. In that case, the number of electrons will be the same as the number of protons. But it is the proton count that sets or determines atomic number.

∙ 11y agoIt is the number of protons and neutrons added together. It does not include electrons since the weight of an electron is less than 1/1000 of a proton and neutron (negligible), but if you want it to be perfectly accurate, they would need to be added in too. Then again, it would complicate things further, so in summary, atomic number = number of protons + number of neutrons.

Is it true that the element's mass number determines how the compound will form?
No. The element's atomic number determines how it forms compounds.
The atomic number of an element determines its?
The atomic number of an element is determined by the number of protons in its nucleus.
What determines the element that an atom belongs to?
Its atomic number. In other words the number of positive protons in the nucleus of each atom and the number of negative electrons surrounding the nucleus of each atom.
From it's atomic number of 15 it is possible to predict that the phosphorus atom has?
15 protons. Atomic number determines the number of protons which the element has
Is the atomic number of an atom equal to the number of protons or neutrons or electrons in the nucleus?
No, atomic number equals the number of protons.The number of neutrons is NOT specific to an element, and various atoms of the same element can have different numbers of neutrons - these are called isotopes.
The atomic number determines the what?
The number of protons.
What is the number of protons in one atom of an element determines the atom?
The number of protons determines the element's atomic number. When combined with the number of neutrons, it determines the element's atomic mass.
Is the atomic number of an element determined by its number?
Protons. This determines what material the element is.
Is it true that the element's mass number determines how the compound will form?
No. The element's atomic number determines how it forms compounds.
The atomic number of an element determines its?
The atomic number of an element is determined by the number of protons in its nucleus.
What part of an element determines it's atomic number?
The number of protons in the nucleus of the atom.
What is it that determines the atomic number of the element?
The number of protons in each nucleus of an atom of the element.
What the atomic number determines?
The atomic number is equal to the number of protons in a chemical element.
Does an element have the same number of protons and atomic number?
Yes. The number of protons is what determines atomic number.
Which of the following determines the identity of an element atomic number mass number atomic mass or overall change?
atomic number
What atomic particle determines the isotope of an element?
The number of neutrons.
Which particle determines the atomic number of an element?
The atomic number of an element is determined by the number of protons.
