Would you find calcium uncombined in nature?
egg shels
Would you expect to find lithium as an uncombined element in nature?
No, lithium is very reactive metal and you would expect it find it as one of the ions ion present in minerals.
Would you expect to find calcium chloride in ocean water?
what do you expeat to find in calcium chloride in ocean water
What element would you expect to behave the most like calcium?
Calcium is in group 2/IIA, so the other elements in that group would be expected to behave most like calcium.
What kind of poetry would you expect to find in the Hebrew Bible?
You would expect to find poetry of a religious nature.
You would not normally expect to see images from nature when viewing the works of?

If one adds 5 grams of sodium chloride and 5 grams of calcium chloride to water at what temperature would you expect the solution of sodium chloride and calcium chloride to boil?
You get salt at the bottom of the pan!
Water in central Texas comes from the Edwards Aquifer and tends to be hard. Which of the following would you expect to find in this water?
A. Calcium ions (APEX)
What do you call metals that are uncombined with other elements?
You would call them pure metals or simply elements, when a metal is mixed with another, usually for dual properties (e.g steel and aluminum alloy - in planes because it is light and strong) it is called an Alloy.
Would you expect to find calcium metal used in conducting wire or structural materials?
Calcium metal is not typically used in conducting wire due to its high reactivity with moisture and oxygen. However, calcium is used in some structural materials, such as certain alloys and as a deoxidizer in steel production.
What type of chemical bond would you expect between a calcium atom Ca atomic number twenty and a chlorine atom Cl atomic number seventeen?
You would expect an ionic bond between a calcium atom (Ca) and a chlorine atom (Cl) due to the large difference in electronegativity between the two atoms. Calcium will donate electrons to chlorine, resulting in the formation of Ca2+ and Cl- ions that will be attracted to each other due to their opposite charges.
Why was calcium discovered?
Calcium was discovered by Sir Humphry Davy in 1808 through the process of electrolysis. He isolated calcium metal by passing an electric current through molten calcium chloride. This discovery helped in understanding the nature of elements and their properties.
