Elements
The smallest subatomic particle of an element is this.
What is: an Electron?
The three subatomic particles that make up a atom.
What are: Protons, Neutrons, and Electrons?
The bond responsible for water's surface tension.
What is: a Hydrogen Bond?
Ice floats on water because of this.
What is: because ice is less dense than water?
Anything that has mass and takes up space.
What is: Matter?
The four most common elements in most living things.
What are: Carbon, Hydrogen, Oxygen, Nitrogen?
(CHON)
The nucleus of an atom is made up of these.
What are: Protons and Neutrons?
A covalent bond is formed as a result of this.
What is: the sharing of electrons?
The states of matter that water can be found in.
What are: a Solid, Liquid, and Gas?
A pure substance that cannot be further broken down is called this.
What is: an Element?
What are: 1 Oxygen atom and 2 Hydrogen atoms?
The space surrounding the nucleus of an atom contains these.
What are: Electrons?
The name given to the electrons that determine an atoms level of reactivity.
What are: Valence (or outermost) Electrons?
The property of water that allows it to move upwards against the force of gravity.
What is: Capillary Action (Cohesion and Adhesion)?
If an atom contains 11 protons and 12 neutrons, it's atomic number is this.
What is: 11?
Atomic mass is calculated by adding these two subatomic particles.
What are: Protons and Neutrons?
This type of ion is produced when an atom loses an electron.
What is: a cation?
A chemical bond formed by the transfer of electrons is called this.
What is: an Ionic Bond?
Water is made up of polar molecules, which means these atoms have the following charges.
What is: Oxygen is slightly negative, and the Hydrogens are slightly positive?
The term for a substance formed by the chemical combination of two or more elements in a fixed ratio.
What is: a compound?
This group of elements are inert, meaning that they are not reactive.
What are: the Noble Gases?
Isotopes are atoms of the same element that have a different number of these.
What are: Neutrons?
The number of bonds that Carbon will make.
What is: Four?
When salt is dissolved in water, water acts as this.
What is: a solvent?
Substances that resist changes in pH are these.
What are: Buffers?
