Solution mining is an example of [blank_start]liquid[blank_end] mining.

The boiling point of Oxygen is -196ºC

The formula for Ammonia is NH3?

The formula for sodium sulfate is Na2CO3?

a [blank_start]vacuum[blank_end] is an example of nothing.

If lithium has an atomic number of 3 and a mass number of 7, the correct number of protons, neutrons, and electrons, respectively, is:

If Magnesium has an atomic number of 12 and a mass number of 24, the correct number of protons, neutrons, and electrons, respectively, is

The chemical element number for Potassium is [blank_start]19[blank_end]

atomic number = number of [blank_start]protons[blank_end].

Which of the following are organic compounds? (3 answers)

Metal atoms form positive ions (cations) by passing [blank_start]electrons[blank_end] to non-metal atoms.

A metal ion has fewer electrons (-) than protons (+), so has an overall positive charge.

Metal atoms transfer outer electrons to non-metal atoms, leaving a shell of [blank_start]eight[blank_end].

Group 1 elements have how many electrons in their outer shell?

The chemical number for Manganese (Mn) is

When non-metals react with each other they form covalent bonds, not ionic. The atoms share enough [blank_start]electrons[blank_end] to achieve the noble gas structure.

Which type of bonding does chlorine gas (Cl2) and ethanol (C2H5OH) have?

An ion is

A compound will have an ionic structure if it is made from

When Sodium reacts with Chlorine, Sodium will

The giant ionic structure of an ionic compound is called an ionic lattice.

Ionic compounds are brittle and shatter when hit.
