How many protons, neutrons and electrons does calcium have? What is the molecular weight of CaCl2? What is the formula for calcium oxide? What is the mass number of cobalt? What is the formula for calcium carbonate? What is the mass number of argon? What is the mass number of strontium...
46Ca and 48Ca are the first "classically stable" nuclides with a six-neutron or eight-neutron excess respectively. Although extremely neutron-rich for such a light element, 48Ca is very stable because it is a doubly magic nucleus, having 20 protons and 28 neutrons arranged in closed shells....
What element is a metal with 4 electrons in its outer shell? What is more reactive, calcium or magnesium? What is the chemical formula for calcium hydroxide? What chemical element is Sb? What is the formula for calcium fluoride? How many neutrons are in calcium?
Because an atom has the same number of protons and electrons, you know that one atom of calcium also has 20 electrons.Answer and Explanation: Calcium is a silvery-colored metal. It is hard and very reactive. As one of the alkaline earth elements, it reacts with both air and water, ...
