My alkali earth metal is calcium. Calcium has an atomic number of 20, so it has 20 protons and 20 electrons. Its atomic mass is 20, so it has 20 neutrons. The Chemical symbol is Ca. Calcium is the most abundant metal in animals, forming teeth, bones and shells.
Calcium is in seawater and in the earth's crust.
Calcium has many practical uses including the extraction and production of other metals, the formation of cheese and in making cements and mortars.
Got all three questions right... interesting to read.
Very interesting and witty article. "So, it turns out that an amount of any chemical compound that is equal to the combined atomic weights or the molecular weight, expressed in grams, contains 602,213,670,000,000,000,000,000 molecules" - A mole.
Hi Jillian,
ReplyDeleteAlthough your post is short for week 6, I found it really easy to read and appreciate you writing out the main points for what calcium is and its practical uses. For such a common element, we should really know more about it :)
