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 stands out from other elements because of its abundance in the Earth's crust, its essential role in biological processes such as muscle contraction and bone formation, and its ability to form strong bonds with other elements due to its two available electrons in the outer shell.
they are all in the same period in the periodic table, they all have the same valance number
No compounds are metals. All metals are elements, although some metals (e.g. brass) are mixtures of metals.
Copper, calcium, and bromine are all chemical elements found on the periodic table. They each have unique properties and are essential for various chemical processes. Additionally, they all play important roles in biological systems - calcium is crucial for bone health, copper is a cofactor in many enzymes, and bromine is used in disinfectants and flame retardants.

They are all elements.
The element calcium is found in all four items.
All elements other than carbon are likely to form inorganic compounds, and even carbon is at least sometimes found in inorganic compounds such as calcium carbonate.

Chalk is composed mainly of calcium carbonate and calcium sulfate, both of which are chemical compounds. So, chalk does not have a fixed number of elements, as it consists of multiple elements bonded together to form these compounds.
Calcium has 2 valence electrons, like all Group 2 elements.
