Calcium (element number 20) has 20 protons and 20 electrons.
Um, the element calcium? Protons, neutrons, electrons..
Calcium is an element, which means that it is made up protons/electrons and neutrons. Each calcium atom contains a total of 20 protons/electrons, and 20 neutrons.
Calcium has 20 protons, 20 electrons and 20 neutrons in its most commonly found isotope.
Calcium has twenty protons and twenty electrons. The main isotope of calcium also has twenty neutrons.
Calcium (element number 20) has 20 protons and 20 electrons.
Calcium has 20 protons and electrons. The symbol for calcium is Ca and its atomic number is 20.
Um, the element calcium? Protons, neutrons, 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.
Calcium is an element, which means that it is made up protons/electrons and neutrons. Each calcium atom contains a total of 20 protons/electrons, and 20 neutrons.
Each calcium atom has 20 protons and 20 electrons. This is because the atomic number, which is 20 for calcium, represents the number of protons in the nucleus of its atom, and in a neutral atom, the number of electrons is equal to the number of protons.
Sodium (Na) is a chemical element with 11 protons and 11 electrons.
Calcium has twenty electrons in each atom.
In the element calcium (Ca), there are 20 protons, 20 electrons, and typically 20 neutrons in the most common isotope, which has a mass number of 40.
The element that has 20 neutrons is calcium. Calcium has an atomic number of 20, which means it has 20 protons in its nucleus. Since the number of neutrons is determined by subtracting the atomic number from the atomic mass, calcium, which typically has an atomic mass of around 40, will have 20 neutrons.
Calcium has 20 protons, 20 electrons and 20 neutrons in its most commonly found isotope.
Calcium has twenty protons and twenty electrons. The main isotope of calcium also has twenty neutrons.
