No, in fact, they rarely are equal. There are different forms of the same type of atom. For example, there are three isotopes of Hydrogen, an element that has one proton. Hydrogen-1 has no neutrons. Hydrogen-2 has one neutron. Hydrogen-3 has two neutrons.
Protons, neutrons, and electrons are subunits present in equal numbers in an atom. The number of protons in an atom is equal to the number of electrons, while the number of neutrons can vary in different isotopes of an element.
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
The number of protons in an atom is equal to its atomic number, which identifies the element. Neutrons are found by subtracting the atomic number from the mass number. For a neutral atom, the number of electrons is equal to the number of protons.
False as a generalization but true for some isotopes. The atomic number is the number of protons in a nucleus, which may coincidentally be the same as the number of neutrons but is not required to be.
The atomic number of an atom is equal to the number of protons in the nucleus. It determines the element's identity and position on the periodic table. Electrons and neutrons can vary in number to form different isotopes of the element.
No
Often, but not always, atoms with an equal number of protons and neutrons in the nucleus are stable and not radioactive.
The number of protons and neutrons is not equal. The equality is not a rule.
protons and electrons will always be = number
Electrons are equal to the number of protons and the atomic number. To find the number of neutrons you must subtract the atomic number from the mass number.
Protons, neutrons, and electrons are subunits present in equal numbers in an atom. The number of protons in an atom is equal to the number of electrons, while the number of neutrons can vary in different isotopes of an element.
No. The number of neutrons has no affect on the number of protons and electrons.
atomic weight = mass of protons + mass of neutrons
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
No An atom may have less, the same, or more neutrons than protons. The number of neutrons determine which isotope of an element you have. You do expect the number of protons and electrons to be the same however. If an atom loses or gains an electron to cause the number of electrons and protons to be mismatched we call that an ion rather than an atom.
Protons
The mass number = protons + neutrons
