The number of protons in one atom of any isotope of calcium is 20, which is the atomic number of calcium.
Calcium has 20 protons and electrons and a variable number of neutrons, depending on the isotope.
Calcium has 20 protons, 20 electrons and 20 neutrons in its most commonly found isotope.
An atom's atomic number tells us how many protons it has. If we reference a periodic table, we see that calcium's atomic number is 20. Thus, calcium has 20 protons.
16 protons in a sulfur-32 isotope because keep in mind that the number of protons in a chemical determines what that chemical is so its not even reasonable to ask how many protons does a sulfur-32 isotope have.
Promethium has 61 protons and electrons; For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope - 61
Calcium has 20 protons and electrons and a variable number of neutrons, depending on the isotope.
Calcium has 20 protons and electrons and a number of neutrons different for each isotope..
The number of protons in an element will be the same regardless of the isotope or ion. To have a different number of protons would change what type of element it is. So, it is not necessary to say "how many protons does calcium-41 have?" because it is the same as saying "how many protons does calcium have?" The answer is the same in any case, the same as the atomic number, 20.
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.
mass number = number of protons + number of neutrons. 47 = 20 + neutrons, so neutrons equal 27.
Calcium atoms have 20 protons and 20 electrons. The number of neutrons varies with the isotope.
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.
Calcium-45 has 20 protons (since it is calcium) and therefore, it has 25 neutrons, as the atomic number (number of protons) subtracted from the mass number (protons + neutrons) gives the number of neutrons.
Ca-46 is an isotope of the calcium found on the periodic table. The atomic number is equivalent to how many protons the atom has and tells the identity of the element, if the number of protons is changed/ atomic mass number, the element would transmutate into another element. Thus, Ca always has 20 protons. Because it is not Ca++ or Ca- it is not changing the charge so no electrons are moving either. This means the number 46 is refering to a change in neutron in the nucleus of the atom, hence it is called an isotope. 46 is the number of protons plus neutrons so the isotope of Calcium has 20 protons, 20 electrons and 26 neutrons, or 46-20=26. Hope this clarifies things.
Calcium has 20 protons, 20 electrons and 20 neutrons in its most commonly found isotope.
There are 20 p , n , e- in an atom of calcium. Its atomic number is also 20.
Calcium has 20 Protons. You can determine the amount of Protons in an Element by checking the top number of an element. This is called the Atomic number. Calcium has 20 protons
