Atomic Structure
These are the two types of particles that you will find at the center of every atom (except Hydrogen).
Protons and Neutrons
The column of elements on the far right of the Periodic Table are called this. Fitting, since they don't want to bond with any other atoms.
Noble Gases
Fittingly, these are the kinds of bonds that form between metals.
In the molecular formula
AgF2
there are this many atoms of Florine (F).
Two
This chemical is the opposite of an acid, chemically speaking.
Base
The reason we have different elements is because of this part of the atom.
The Proton
You don't commonly see these elements, found at the bottom of the Periodic Table.
Rare Earth elements
Nonmetals don't like letting go of their electrons. That's why they do this instead.
Share Electrons
In the chemical formula
2H2 + O2 -> 2H2O
there are this many molecules of water.
Two
The basis of acids and bases is in Hydrogen Ions and Hydroxide Ions, which are two parts of this chemical.
Water (H2O)
The electrons are the reason we have chemical reactions. Protons and Neutrons instead cause these kinds of reactions.
Nuclear reactions
Oxygen, Nitrogen, and Carbon are all in this group. They're some of the most common elements you will find on Earth.
Nonmetals
When an Ionic bond forms between Sodium and Chlorine, this one would give up its electron in the exchange.
Sodium
In the chemical formula
KMnO4
There are this many Manganese (Mn) atoms.
1
Potassium Hydroxide is a this kind of chemical.
Base
The electrons don't just fly around wherever they want. They hang out in shells, especially this one on the outside.
The Valence shell
The atomic number of Sodium is this. Don't be fooled by the name, it's chemical symbol is Na.
11
In a mixture of Sodium (Na), Carbon (C), Oxygen (O), and Florine (F), this one is the only one that would not form a covalent bond.
Sodium (Na)
This is the chemical formula for Carbon Dioxide.
CO2
When the Hydrogen atom detaches from the water molecule, it leaves this behind, turning it into a Hydrogen Ion.
electron
Each of the atom's shells hold a specific number of electrons. The one at the center has this many, the next shell out has this many, and the next one has this many.
2, 8, and 8
These elements all have 2 valence electrons, which is why they are all in the same family.
Alkali Earth Metals
Carbon is a very important element in chemistry, mostly because it can form this number of bonds and bonds easily to lots of different elements.
Four
When a molecule of glucose (C6H12O6) reacts with Oxygen (O2), it can create this many molecules of water (H2O).
6
When the following acid-base reaction happens,
HCl + NaOH -> _____ + H2O
this salt is created.
NaCl
Sodium Chloride
