False. The number of electrons always equals the number of protons for an element and this is called the atomic number of an element. The number of neutrons in an element depends on other factors and varies by element and the same element can have different versions with a different number of neutrons. Each version is called an isotopes. The sum of the protons and neutrons in an atom is called the atomic weight.
Hydrogen has three isotopes with 0, 1, or 2 neutrons, with atomic weights 1,2, 3). Isotopes with 1 or 2 neutrons are extremely rare.
Carbon has four isotopes. It can have 5, 6, 7, or 8 neutrons (atomic weights 11, 12, 13, 14). We commonly refer to different isotopes by its name and weight as in carbon-11, carbon-12, carbon-13, carbon-14. Carbon-12 is common and everywhere. the others are very rare. Carbon-11 and carbon-14 are considered unstable and tend to brake down into other elements over a period of time releasing energy as it happens. This is called radioactivity.

What is the protons neutrons and electrons for 65Zn?
Protons- 30 Electrons- 30 Neutrons- 35 Zn-65 means the atomic number plus the number of neutrons equals 65. Zinc always has 30 protons; therefore, it's atomic number is 30 and it has 30 protons and electrons. The remaining number is the neutrons: 65-30= 35
The sum of the protons and neutrons in an atom equals the .?
atomic number
How many protons and neutrons are there in the nucleus of an atom that has an atomic number of 84 and a mass number of 210?
84 protons, the same as the atomic number, and (210 - 84) or 126 neutrons. The numbers of protons and neutrons together equals the mass number.
The combined number of protons and neutrons?
The combined number of protons and neutrons is known as the mass number of an atom. It can be used to calculate the atomic mass by adding the total number of protons and neutrons in the nucleus of an atom.
How do the numbers of protons neutrons and electrons for an element compare?
In the neutral state, all atoms of the same element contain equal numbers of protons and electrons. However, most elements have atoms with different numbers of neutrons. These are called isotopes.
Is it true that the number of protons always equals the number of neutrons in all isotopes?
No. the statement is false.Number of positively charged protons always equals number of negatively charged electrons in a neutral atom
An atoms mass number equals the combination of what two things?
The mass number of an element is equal to the sum of the elements neutrons and protons.
WHAT Equals the sum of the number of neutrons and protons in an isotope?
The atomic mass equals neutrons and protons. This is true in non isotopes as well.
What is the symbol of an ion that has 20 protons 20 neutrons and 18 electrons?
The atomic number always equals to the number of protons. which in this case, is 20
What equals atomic mass minus protons?
Roughly, the number of neutrons. Note that the atomic mass is only approximately equal to the number of protons plus the number of neutrons - there is a relatively small discrepancy, due to the binding energy.
Does the number of neutrons always equal the number of protons?
No
Is there always an even number of protons and neutrons?
No
Are there always the same number of protons and neutrons as electrons in a Bohr model?
In a Bohr model of an atom, the number of protons typically equals the number of electrons, making the atom electrically neutral. However, the number of neutrons can vary; atoms of the same element can have different numbers of neutrons, resulting in isotopes. Therefore, while protons and electrons are usually equal, neutrons can differ in number.
What is the Mass number of helium atom that has two protons and two neutrons?
4 because the mass number equals protons plus neutrons. Which is 4.
What is the mass number of helium that's has two protons and two neutrons?
4 because the mass number equals protons plus neutrons. Which is 4.
What is the protons neutrons and electrons for 65Zn?
Protons- 30 Electrons- 30 Neutrons- 35 Zn-65 means the atomic number plus the number of neutrons equals 65. Zinc always has 30 protons; therefore, it's atomic number is 30 and it has 30 protons and electrons. The remaining number is the neutrons: 65-30= 35
What is the sum of the protons and neutrons in an atom equals to?
The nucleon number (or mass number).
