100
Out of these samples the one that is a compound: Helium, Gold, Nickel, Methane and why.
What is Methane and it is a compound due to more than one element is contained within it?
100
The name of the elements that have 8 Valence electrons and are stable.
What are noble gases?
100
In polar molecules this is the way that valence electrons are shared.
What is unequal?
100
These bonds are between metals and non metals and between positive and negatively charged atoms.
What is an ionic bond?
200
The picture of a molecular model of CH4 drawn as a ball and stick model.
What is there is a center circle with 4 straight lines leading out to 4 smaller circles?
200
The reason why water is polar and the name given to it as it dissolves so many other substances.
What is shares electrons (covalent bond) and the name given to it is the "universal solvent"?
200

What is 2,8,18?
300
The name of atoms that gain e- and lose e- during a bonding of 2 elements.
What is a anion, cation?
300
These can be single, double or triple and form molecules, these can also be between non metals.
What is covalent bonds?
300
This type of bond "transfers electrons".
What is an ionic bond?
400
The reason why water is a covalent bond.
What is water is 2 nonmetal atoms which share electrons forming a molecule?

The elements at the far left of the periodic table are this and 3 characteristics of what they do when they bond.
What is a metal, 1. The bonds are metallic so: the electrons are pooled, there is a "sea" of electrons shared among positively charged metal atoms?
400
This is an atom that is no longer electrically neutral and the 2 possible names for them. **they have charges but are stable**
