Calcium.
YES, it's is the calcium that makes the water "hard". That is why you use a cleaner that has a calcium remover in it to get those hard water stains off.
The chemical element that is hard, black, and shiny is boron. Boron is a metalloid found in Group 13, and it has the atomic number of 5 on the periodic table.
Magnesium is the element described. It is a silvery solid, fairly hard, and commonly found in upset stomach remedies like antacids. When burned, magnesium emits a bright light due to its high reactivity with oxygen in the air.
The presence of hard water can affect the process of boiling water by causing mineral deposits to form on the heating element or inside the pot. This can reduce the efficiency of heat transfer and increase the time it takes for the water to reach boiling temperature.
Cobalt is an element on the periodic table. It is a grey metal that is hard and found near copper in underground mines.
The key element is calcium.

Calcium
Calcium is the trace element most important for making bones hard. It is a key component of bone tissue and is necessary for maintaining bone density and strength. Without adequate calcium intake, bones can become weak and brittle.
The elements y and u in hard water usually refer to calcium (y) and magnesium (u) ions. These minerals are responsible for making water hard, which can lead to issues like scaling in pipes and reduced efficiency of soap.
Calcium is the trace element most important for making bones hard. It is a major component of bone tissue and plays a crucial role in bone mineralization.
soft you can bend and hard you can not
You find them throughout the body in adults but more are soft cartilage in babies.
Seal's bones are hard.
It is not an element... for hard water usually a build up calcium compounds.
Bones and cartilage are found in most all vertebrates, with the exception of sharks and rays, which only have cartilage.
Calcium and magnesium are the main metals found in hard water areas. These minerals dissolve in water as it passes through rocks like limestone and chalk, leading to the formation of hard water.
