Atomic
What are the basic building blocks of matter?
What are Atoms?
This is the abbreviation for the element Hydrogen.
What is H?
All atoms seek to be stable and stability comes from having these filled.
What are energy levels?
This is the chemical formula for water.
What is H2O?
When water molecules stick together.
What is Cohesion?
Atoms are made of these positively charged components
What are protons?
The letter P represents this element.
What is phosphorus?
The lowest energy level is closest to the nucleus and can occupy up to this number of electrons.
What is 2?
This is a molecule category in which the total charge is zero, but the charge is unevenly distributed over the molecule (like we see with water).
What is polar?
Any substance in which other substances are dissolved (typically a liquid)
What is a solvent?
All atoms have the same number of protons and these, negatively charged particles.
What are electrons?
This is a collection of atoms that all have the same number of protons.
What is an element?
Elements are stable when their energy levels are this.
This type of bond is a weak electrical attraction between a partially positive hydrogen atom and a partially negative atom of another molecule (usually oxygen or nitrogen).
What is a hydrogen bond?
An attractive force that holds molecules of different substances together.
What is adhesion?
This is the specific number of protons, which distinguishes one atom from another.
What is the atomic number?
These elements have the same number of protons, but a different number of neutrons.
What are isotopes?
This type of bond causes electrons to be transferred from one atom to another.
What is ionic?
Unlike most molecules, solid water floats on liquid water. This is because water is less _______ as a solid than a liquid.
What is dense?
Water absorbs a lot of heat (thermal) energy before changing temperature, which is because of this characteristic.
What is High Heat Capacity?
These atoms have gained or lost electron(s)
What are ions?
This is the sum of the protons and neutrons in an atom.
This type of bond is caused when atoms share electrons to fill their outer energy levels. The more electrons shared the more bonds it has.
What is a covalent bond?
A solution where water is the solvent.
What is an aqueous solution?
Molecules at the surface of a liquid absorb enough energy to break bonds and escape into the air as a gas.
What is evaporation?
