Why are some elements stable on their own while others are more stable in compound?

Some elements are stable on their own because they have a complete outer energy level. These elements are called noble gases. Hydrogen and Helium have a complete energy level with two electrons and all of the other elements are stable with eight. When an element doesn't have a complete outer energy level it is stable in a compound. This is because it is being combined with another element to complete it's energy level.

How do periodic trends illustrate and change in chemistry?
Periodic trends illustrate how some elements are very reactive while others are stable.

Explain why some elements are stable on their own while others are more stable in compounds?
its because some are naturally stable like helium, when some like hydrogen have an extra electron in their electron clouds. That's why they are unstable. When they meet with an element with one extra electron they can be stable because the first electron cloud holds 2 electrons. ex. : hydrogen - 1 electron hydrogen - 1 electron adding both together will give you a full eletron cloud. Hope this helps!
What is the formula for an ionic compound that contains the elements magnesium and chlorine?
Magnesium ions have a 2+ charge, while chloride ions each have 1- charge. In order to cancel out the charges to create a stable, neutral compound, the formula must be MgCl2.
Why can iron be used to extract copper?
Iron is a more reactive metal than copper, and so will replace it in a compound. The more reactive a metal is, the more stable it is in a compound, and the less stable it is in its elemental form. So relative to one another, iron is more stable in a compound while copper is more stable as apure element.
How do you determine the number of elements using the formula of a compound?
an element is a single substance while a compound is made up of multiple elements. Theirs no way to now how many elements form to make a compound... only through a microscope/
What are two ways a compound is different from a element?
Elements make up compounds. Elements are purely one substance, while a compound is formed by chemical bonds between two or more elements.
Why are some elements so rare while others appear frequently?
The element my be rare because it is part of a compound and cannot be found as an element as itself in nature. The only way to get the element is to extract it from the compound. That may not be very easy.
