Because it has the same kind of atoms through and through. Calcium doesn't contain anything else than calcium. And anything that consists of only one kind of atoms is an element.
Oxygen and calcium are both elements found on the periodic table. They are different in terms of their chemical properties - oxygen is a nonmetal, while calcium is a metal. Additionally, they have different atomic numbers and atomic masses.
Calcium is different from all other elements in Group 2 of the periodic table because it has a higher electronegativity and a stronger metallic character compared to the other elements in the group, such as magnesium and strontium. Additionally, calcium has a higher ionization energy and a greater tendency to form ionic compounds compared to the other Group 2 elements.
Calcium is unique because it plays a crucial role in biological processes such as bone formation, muscle contraction, and nerve function. It is the most abundant mineral in the human body and is necessary for overall health. Unlike other elements, calcium has a distinct presence in the structure and function of living organisms.
In compounds consisting of a metal and nonmetal, the metal (calcium) is written first and the nonmetal (sulfur) has the end replaced with -ide. So the correct name for a compound of calcium and sulfur is calcium sulfide.
Calcium, oxygen, and carbon are common elements found in carbonate minerals. Other elements such as magnesium, iron, and manganese can also be present depending on the specific mineral. These elements combine with carbonate ions to form minerals such as calcite (calcium carbonate) and dolomite (calcium magnesium carbonate).
its number of protons

Its made from different elements
Calcium is different from all other elements in Group 2 of the periodic table because it has a higher electronegativity and a stronger metallic character compared to the other elements in the group, such as magnesium and strontium. Additionally, calcium has a higher ionization energy and a greater tendency to form ionic compounds compared to the other Group 2 elements.
Calcium is itself an element. Elements do not contain other substances.
Yes it does react strongly when bonding with other elements

It combines with Oxygen the most.
The main elements found in teeth are calcium, phosphorus, and trace amounts of other minerals such as fluoride, potassium, and sodium.
Yes, calcium chloride is a compound because it is made up of at least two elements chemically bonded together.
Egg yolk contains calcium, iron, magnesium, phosphorus, potassium, zinc and many other elements. Eggs are a good source of may different vitamins and amino acids.
no. calcium itself is not magnetic, but if it is mixed with other elements (iron, etc.) then it will be. :) hope i helped!
