Building Blocks
This substance takes up space and has mass.
Matter
Its a subatomic particle with a negative charge.
Electron
What property makes something sink or float?
Density
This is the strongest bond in living things.
Covalent
Water temperatures don't change quickly. The property that accounts for this is its high....
Specific Heat
This substance cannot be broken down by chemical reactions.
Element
The mass number of an element is the sum of these two parts.
Protons + Neutrons
He designed the model of an element that includes the valence shell.
Bohr
This bond forms between a cation and an anion.
Ionic
This word describes water's partial charges on the opposite ends of the molecule.
Polar
Humans need 19 of these to survive.
Essential element
The atomic number tells us the number of this subatomic particle.
Protons
This force allows geckos to stick to walls.
Van der Waals interactions
When two valence electrons are shared it's called this.
Double covalent bond.
This term describes something that does not interact well with water and will not combine with it.
Hydrophobic
This element makes up 65% of human body weight.
Oxygen
The atomic number of hydrogen is 1. The mass of hydrogen is 1. How many neutrons does hydrogen have?
Zero
An isotope has the same number of protons but a different number of these compared to its elemental equivalent.
Neutrons
In a hydrogen bond, the hydrogen has this partial charge.
Partial positive
They may be weak but they account for much of water's super powers.
Hydrogen bonds
A subatomic particle with no charge.
Neutron
Its the name of a subatomic particle found in the outermost shell.
Valance electron
In a periodic table, columns all have the same number of these.
Valence electrons
This form of a covalent bond involves partially charged atoms.
Polar covalent bond.
