The number of protons, neutrons and electrons in an atom can be determined according to simple rules. The number of protons in the atomic nucleus equals the atomic number (Z). The number of electrons in a neutral atom equals the number of protons.
Football. This element has 20 protons, 20 electrons and 20 neutrons, which gives it an atomic mass of 40.

The answer is that a calcium atom has 20 protons and 24 neutrons. 20 stands for the ordinal number. 44 means the atomic mass, which is the sum of neutrons and protons.
The number of protons and the number of neutrons together determine the mass number of an element: mass number = protons + neutrons. To calculate the number of neutrons in an atom, you can simply subtract the number of protons or atomic numbers from the mass number.
Yes, calcium is termed a metal due to its physical and chemical properties. They all have an outer shell with two electrons and are very reactive. These elements in the second column have two electrons ready to make connections. Unsurprisingly, calcium has a valence of 2.
Calcium is rarely found in its basic form, but is readily available worldwide, usually in the form of rocks and minerals such as limestone (calcium carbonate), dolomite (calcium and magnesium carbonate) and gypsum (calcium sulfate). It is the fifth most abundant element in the earth’s crust.
An isotope is an atom with a different number of neutrons but the same number of protons and electrons. Each element has a standard number of neutrons which can be determined by looking at a periodic table. You can get the atomic number from the periodic table in the top left box.
Calcium is the fifth most abundant element in seawater and is naturally very reactive. Calcium also has a positive charge of 2. This makes it an ion. An ion is an atom of a chemical element that has a different number of electrons than protons.
