Answer:
In nature the atoms of noble gases do not bond either with other gases or with each other. Helium exists as atoms of Helium not as diatomic molecules. Some of the larger noble gases can be made to form molecules. This does not normally happen in natural conditions.
Explanation:Noble gases are odorless, colorless, nonflammable, and monotonic gases that have low chemical reactivity. The full valence electron shells of these atoms make noble gases extremely stable and unlikely to form chemical bonds because they have little tendency to gain or lose electrons.
Answer:
A control variable in scientific experimentation is an experimental element which is constant and unchanged throughout the course of the investigation.

Due to Kr-42 the 20mg will diluted to the experinental evluation
Answer:
Explanation:
The objective here is to draw the Lewis structure for the polyatomic trisulfide anion and to be sure all resonance structures that satisfy the octet rule are included.
The Lewis structure for Polyatomic trisulfide anion
The first step is to the layout the skeleton of the Polyatomic trisulfide anion
S S S
However, the next step is to make sure we fill in the bonding pairs of electrons on the central atom.
Then , we move over to filling the lone pairs electrons before we finally have the Lewis structure for Polyatomic trisulfide anion as shown in the image below.
