if an atom has a mass number of 32 and it has 20 neutrons in the nucleus, what is the atomic number of this atom?
12 protons
What else can I help you with?
Mass number - atomic number?
The mass number represents the total number of protons and neutrons in the nucleus of an atom. The atomic number specifies the number of protons in the nucleus. The difference between the mass number and atomic number gives the number of neutrons in the nucleus.
Atomic mass is determined by the number of protons plus the number of?
neutrons in an atom's nucleus. It is measured in atomic mass units (amu) and provides the total mass of an atom. The atomic mass is approximately equal to the sum of the protons and neutrons in the nucleus, as the mass of electrons is negligible.
The number of neutrons in the nucleus of an atom can be calculated by what?
The number of neutrons in the nucleus of an atom can be calculated by subtracting the number of protons (atomic number) from the atomic mass of the atom. Atomic mass - Atomic number = Number of neutrons.
Is atomic mass the amount of neutrons in the nucleus in the atom?
atomic mass = number of neutrons + number of protons.
What contributes to an atom's atomic number and to its mass number?
An atom's atomic number is determined by the number of protons in its nucleus, which are positively charged. The mass number is the sum of the protons and neutrons in the nucleus, as neutrons contribute to the atom's mass but not its charge.
How many neutrons are in the nucleus of an atom that has an atomic mass of 36 and an atomic?
To find the number of neutrons in an atom, you subtract the atomic number (which represents the number of protons) from the atomic mass. If the atomic mass is 36 and the atomic number is, for example, 18 (like Argon), you would calculate it as 36 - 18 = 18 neutrons. Thus, the atom would have 18 neutrons in its nucleus.
Neutrons in the nucleus of an atom calculated?
Mass number minus atomic number = number of neutrons
The sum of protons and neutrons in the nucleus of an atom is the?
Atomic Mass. This can vary depending upon the number of neutrons in the nucleus. Whereupon it is known as an ISOTOPE. Do NOT confuse Atomic Mass , with Atomic Number(Z). The Atomic Number is an elements position in the Periodic Table, AND the number of PROTONS in the nucleus.
What is equal to the total number of protons and neutrons?
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
What are the differences between the atomic number and the mass number of an atom?
atomic no is the no of protones in a nucleus while atomic mass is the sum of protons and neutrons in nucleus of an atom....
An atom of sulfur is represented by 3316S. How many neutrons are in the nucleus of this atom?
The number 33 in "3316S" represents the atomic number of sulfur, which is the number of protons in its nucleus. To find the number of neutrons, subtract the atomic number from the atomic mass. In this case, the atomic mass is 16, so there are 16 - 33 = 16 neutrons in the nucleus.
Is the mass number of an atom equal to the atomic number?
Only if the atom is hydrogen-1! The mass number of the atom is equal to the sum of the numbers of protons, which is the same as the atomic number, plus the number of neutrons. The only non-radioactive atom without neutrons is hydrogen-1.
