Atoms
It is the name of the positive particles in the nucleus of an atom.
What are protons?
What is to the left of the zigzag line (or to the left, of the metalloids)?
This is the type of bond that is made from cations and anions (positive and negative ions).
What is ionic bonds?
This is how you balance the following equation:
__H2 + __O2 --> __H2O
What is:
2H2 + O2 --> 2H2O ?
A nebula is made out of these two main components.
What are gas and dust?
It is what changes, turning an atom into an ion.
What is it gains or loses electrons?
This is the name of the group with stable gases.
What is the Noble Gases (or group 8A)?
What is a covalent bond?
This is what happens to a reaction of baking soda and vinegar when the vinegar is heated up before the reaction.
What is the reaction takes place much faster?
Our sun will eventually end its life, forming this.
What is a white dwarf (or an eternity later, it will eventually turn into a black dwarf)?
This atom is has the lowest atomic number of any noble gas.
What is Helium?
This is the name of the group of the Periodic Table which contains the most highly reactive metals.
What are the Alkali Metals (or Group 1A)?
These two groups on the periodic table form ionic bonds.
What are metals getting together with nonmetals (more specifically, Group 1A atoms bonding with atoms from Group 7A)?
This is the name of a substance which speeds up a chemical reaction but is not changed or used up in the reaction.
What is a catalyst?
A giant blue star, with over 25 solar masses will probably end its life becoming this exotic celestial object.
What is a black hole?
This is what you get when you subtract the atomic number from the rounded off mass number of an atom.
What is the number of neutrons?
This is the name of the group of the Periodic Table which contains the most reactive Nonmetals.
What are the Halogens, (or Group 7A)?
What is they tend to be gases or liquids at room temperature (or solids with low melting points)?
In order to dissolve rock salt more quickly, you could smash it into tiny pieces before dissolving it in water, because of this.
What is an increase of exposed surface area speeds up the dissolving process?
When a Red Giant collapses, it forms this before becoming a White Dwarf.
What is a Planetary Nebula?
Carbon-14 is an example of this, a type of atom which has a different number of neutrons.
What is an isotope?
This is how you can use the Periodic Table to identify the number of valence electrons (or Lewis Dots) in an atom.
What is use the Group number (more specifically, it's groups 1A-8A, and the group number tells you how many dots (or electrons) there are?
When one water molecule gets together with another water molecule, this type of intermolecular bond is formed (Hint: It's what makes water liquid at room temperature, instead of a gas).
What are Hydrogen Bonds?
This is the name of the type of reaction in which the products have more energy than the reactants.
What is an endothermic reaction?
This is formed before a star, when a nebula contracts.
What is Protostar?
