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.
What else can I help you with?
The mass number of an atom of calcium with 20 protons and 20 neutrons is?
The mass number of an atom is the sum of the protons and neutrons in its nucleus. Therefore, for an atom of calcium with 20 protons and 20 neutrons, the mass number would be 40.
The mass number is used to calculate the number of what?
The number of protons and 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
The mass number is used to calculate the number of?
protons and neutrons in an atom. It is the sum of protons and neutrons in the nucleus of an atom.
A common isotope of carbon has a mass number of 13 The total number of protons and neutrons in the nucleus is?
13. The mass number is always the total number of protons and neutrons.
The mass number of an atom of calcium with 20 protons and 20 neutrons is?
The mass number of an atom is the sum of the protons and neutrons in its nucleus. Therefore, for an atom of calcium with 20 protons and 20 neutrons, the mass number would be 40.
The mass number of an atom of calcium with twenty protons and twenty neutrons?
The mass number of an atom of calcium with twenty protons and twenty neutrons is 40. This is because the mass number is the sum of the protons and neutrons in the nucleus of an atom.
How many protons does calcium 47 have?
mass number = number of protons + number of neutrons. 47 = 20 + neutrons, so neutrons equal 27.
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.
What is the mass number of calcium-41?
Calcium is a metal element. Atomic mass of it is 40.
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.
How many protons and neutrons are there in electronic configuration of the atom of calcium?
The number of protons in a calcium atom is always the same as the atomic number of calcium, which is 20. The number of neutrons depends on the isotope. The most common isotope is Ca-40. The number of neutrons is equal to the isotopic mass number minus the atomic number, in this instance, also 20.
How many protons neutrons and electrons will positive two ion of calcium have?
A positive two ion of calcium will have 20 protons, 18 neutrons, and 18 electrons. The number of protons and neutrons in a calcium ion remains the same as in a neutral calcium atom (calcium has 20 protons and about 20 neutrons in its nucleus), but it loses two electrons to become positively charged.
What element is the number of protons and neutrons in the nucleus?
All elements have neutrons and protons within the nucleus.
The mass number is used to calculate the number of what?
The number of protons and neutrons in the nucleus
What is the element that has 20 neutrons?
Several can. Perhaps you meant to ask which has 20 protons, in which case the answer is calcium. (Calcium is also one of the elements that can have 20 neutrons, but it's not the only one.)
What element 20 protrons 20 neutrons and 18 electrons?
The element with 20 protons, 20 neutrons, and 18 electrons is calcium. Calcium has an atomic number of 20, which tells us the number of protons in the nucleus. The number of protons and electrons should be equal for a neutral atom, therefore in this case the element is calcium.
