Periodic Table
The element for H.
What is Hydrogen?
A neutral group of atoms joined by covalent bonds.
What is a molecule?
Anything that has mass and takes up space.
What is Matter?
On this common temperature scale, the freezing point of water is 0 degrees and the boiling point is 100 degrees.
What is the Celsius scale?
These are the three subatomic particles, one positive, one negative, and one neutral, that make up every atom.
The vertical columns on the periodic table.
What is Groups?
When table salt forms, a metal and a nonmetal bond due to the transfer of electrons, creating a force that results in ions.
What is an ionic bond?
This state of matter has a definite volume but takes up the shape of its container.
What is a liquid?
This tool is the most commonly used instrument to measure temperature.
What is a thermometer?
The dense bundle located at the very center of an atom that contains both protons and neutrons.
What is the nucleus?
The 18th group of elements in the periodic table.
What is Noble Gases?
In this type of chemical bond, atoms share valence electrons to achieve a stable electron configuration.
What is a covalent bond?
In this state of matter, molecules move extremely quickly, bounce off each other, have very weak attractions, and fill the entire space of their container.
What is a gas?
This is the specific temperature at which water boils at standard atmospheric pressure, expressed in degrees Celsius.
What is 100 degrees Celsius?
This is the name for atoms of the same element that have the same number of protons but a different number of neutrons.
What are isotopes?
These triplets of the periodic table consist of Iron, Cobalt, and Nickel
What is the Iron Triad?
Two pairs of electrons that are shared between two atoms.
What is a double bond?
The ability of a substance to burn, which can only be observed when a chemical change might happen.
What is a chemical property?
On the Kelvin scale, this temperature is defined as absolute zero.
What is 0 Kelvin?
This is the sum of an atom's protons and neutrons, which determines its mass number.
What is the atomic mass.
This noble gas, element 10, famously gives fireworks their bright color.
What is Neon?
This type of bond involves the unequal sharing of electrons between atoms, resulting in a partial positive charge on one atom and a partial negative charge on the other.
What is a polar covalent bond?
This is the tendency of a physical object to resist changes in its state of motion, and the more massive an object is, the greater this property.
What is inertia?
For $500, this temperature, equivalent to 50 degrees Fahrenheit, is notably not expressed using the word "degrees" in scientific contexts.
What is Kelvin?
The specific outermost electrons of an atom that determine how it interacts and forms bonds with other atoms.
What is valence electrons?
