Well, first, I feel I should point out that if the atomic number is not 20, then it's not calcium.
A neutral atom of calcium has 20 protons and 20 electrons.

Which element has 20 protons 20 neutrons and 20 electrons?
Calcium has 20 protons and electrons. The symbol for calcium is Ca and its atomic number is 20.
How many valence electron does Ca have?
Calcium's atomic number is 20. It therefore has 20 protons and 20 electrons. Since calcium is a group 2 element, 2 of those electrons are valence electrons.
How many protons does calcium-39 have?
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.
How many atoms do Ca have?
There are 20 protons in a calcium atom. You can find the number of atoms in any element by looking at the atomic number which is in the top right corner of the element's box on the periodic table. e.g. Ca 20 40.078
Protons electrons and neutrons in any given atom?
The atomic number of a chemical element is equal to the number of electrons or protons. The number of neutrons = Atomic weight of an isotope (rounded) - atomic number of the element (or the number of protons)
What is the protons and electrons of element calcium?
The element calcium has 20 protons and 20 electrons.
Which element has 20 protons 20 neutrons and 20 electrons?
Calcium has 20 protons and electrons. The symbol for calcium is Ca and its atomic number is 20.
The atomic number of an element is what?
The atomic number of an element is how many protons and electrons (you must have the same amount of protons as electrons) an element has in it's nucleus. The Atomic number= number of protons= number of electrons.
What is the atomic mass the same as?
The Atomic Mass is equal to the number of protons and electrons that an element has.
What is The atomic mass of an element is equal to?
The number of protons, electrons, and neutrons:P
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 can be determined by looking at the atomic number of an element?
the number of protons in an atom and the number of electrons in an atom
Chemical with 11 protons and 10 electrons is?
The chemical element with 20 protons and 20 neutrons is Calcium(Ca). The number of protons is equal to the number of electrons, and the number of electrons is equal to the atomic number.
How many protons does have calcium?
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
How many protons and electrons does a calcium atom have?
Calcium has 20 protons, 20 electrons and 20 neutrons in its most commonly found isotope.
How many protons and electrons are in element with an atomic number?
An element's atomic number is equal to the amount of protons in that element. Each atom has a different number of protons and electrons present in their make-up.
How do you find the number of protons electrons of an element?
The atomic number of the element is the number of protons, therefore there has to be the same amount of electrons to protons.
