What is the number of protons and neutrons in a calcium nucleus?

∙ 14y ago
The atomic number of calcium is 20 and relative Atomic Mass (nucleon number) 40.1. The nucleon number is a decimal because it is an average value having taking all the different isotopes into consideration, based on their relative abundance. So all calcium atoms have 20 protons and 20 electrons. The number of neutrons will depend on what isotope of calcium we are talking about; calcium has 24 isotopes. If we consider the isotope calcium-40, which is the most abundant of all at about 97%, the can determine its number of neutrons as 40 - 20 = 20. So a calcium-40 isotope has 20 neutrons.

The mass number of an atom of calcium with 20 protons and 20 neutrons is?
40, the sum of the protons and neutrons.
If you know the atomic number and the mass number of an isotope how could you figure out the number of neutrons in its nucleus?
The mass number is the total number of protons plus neutrons in the nucleus. The atomic number is the total number of protons in the nucleus. So subtract the atomic number from the mass number and that will give you the total number of neutrons in the nucleus.
What are the subatomic particles of calcium?
Calcium has 20 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a calcium atom = Mass number - 20
A(n) is described as a nucleus of protons and neutrons surrounded by an electron cloud.?
Atomic number is the equivalent of the number of protons in an atomic nucleus.
How many neutrons are contained in an iodine nucleus with a mass number of 132 and an atomic number of 53?
79; the mass number is the sum of the protons and neutrons, and the atomic number is the number of protons. So if you take the mass number (protons + neutrons) minus the atomic number (protons), you get the number of neutrons.
What is tha neutron for calicum?
An atom contains protons, neutrons, and electrons. The electrons are tiny. They can be found in a fast-moving cloud, orbiting the nucleus. Each electron has a charge of -1. The nucleus contains the protons and neutrons, which are packed tightly together. The protons each have a charge of +1, and the neutrons have a charge of zero. The mass number of an element is the number of protons and the number of neutrons added together. Since the number of protons is equal to the atomic number of the element, the number of neutrons can be found by subtracting the atomic number from the mass number.
How many protons neutrons and electrons are in an atom of calcium-42?
Calcium has atomic number 20, which means that all calcium atoms have 20 protons in their atomic nuclei. Neutral calcium atoms also have 20 electrons. Isotopes of calcium vary in the number of neutrons in their atomic nuclei, and are named for their mass number, which is the sum of the protons and neutrons in the nucleus. You can calculate the number of neutrons (N) in an isotope by subtracting the number of protons (atomic number) from the mass number. N = 42 - 20 = 22, therefore, a calcium-42 isotope has 20 protons, 20 electrons, and 22 neutrons.
The number of neutrons plus protons in the nucleus of an atom-?
nass number is the number of neutrons plus protons in the nucleus of an atom
How many protons does an atom of Calcium have in its nucleus?
A calcium ion has 20 protons, the same as its atomic number. The number of electrons depends on the charge on the ion. For the most common calcium ion with a charge of +2, the number of electrons is 18; 20 - 18 = +2. The number of neutrons depends on the isotope that is ionized and is equal to the mass number of the isotope minus the atomic number of 20.
Does a nucleus have the same number of protons and electrons?
The nucleus of an atom contains only protons and neutrons; there are never any electrons in the nucleus. The number of neutrons is generally equal to or greater than the number of protons.
Protons and neutrons in the nucleus add up to give the?
The number of protons added to the number of neutrons in a nucleus give that isotope's atomic weight.
Total number of particles in the nucleus is called what?
There are two types of particles in the nucleus of an atom, which are the Protons and the Neutrons. The number of particles in the nucleus depends what is the element. For example, Oxygen has 8 protons and 8 neutrons in the nucleus and Phosphorus has 15 protons and 16 neutrons in the nucleus.
How is the nucleus related to the periodic table?
The nucleus contains the protons and neutrons. The number of protons determines the atomic number of the element and the number of protons and the number of neutrons together determine the atomic mass.
How many protons does calcium 47 have?
mass number = number of protons + number of neutrons. 47 = 20 + neutrons, so neutrons equal 27.
Is the atomic number of an atom is equal to the number of protons or neutrons in the nucleus?
Protons
What do isotopes and nucleus have in common?
All the isotopes of a chemical element have the same atomic number, number of protons and number of neutrons.
Can the nucleus hold two or more protons?
A nucleus contain protons and neutrons. A nucleus can hold more protons - the number is equal to atomic number.
