Periodic Trends Graphing
On a line graph of Atomic Radius vs. Atomic Number, this element in Period 2 sits at the highest point.
The type of bond formed when electrons are transferred from a metal to a non-metal.
What is an ionic bond?
The positively charged particle found inside the nucleus of an atom.
What is a proton?
As you move down a group on the periodic table, atomic size does this.
What is increases?
The chemical name for the compound NaCl.
What is Sodium Chloride?
The general trend or direction of the line when graphing First Ionization Energy across a period from left to right.
What is an upward/increasing Trend?
The type of bond formed when two non-metals share electrons.
What is a covalent (or molecular) bond?
Atoms of the same element that have different numbers of neutrons.
What are isotopes?
The measure of how strongly an atom attracts shared electrons in a bond.
What is electronegativity?
The prefix used in covalent naming to show that there are four atoms of an element (like in CF4).
What is tetra-?
The group of unreactive gases that form the sharpest on a first Ionization energy graph.
What are Noble Gases?
Ionic compounds generally have high values for these two physical temperature properties.
What are the melting/boiling points?
The maximum number of electrons that can fit into the first energy shell of a Bohr-Rutherford diagram.
Answer: What is 2?
The energy required to remove the outermost electron from a neutral atom.
What is First Ionization Energy?
The total number of valence electrons in a molecule of CO2.
What is 16
On a graph comparing metal reactivity down Group 1, the reactivity line goes in this direction.
What is upward / increasing?
The term for a covalent bond where electrons are shared unevenly between two atoms.
What is a polar covalent bond?
The subatomic particle with such a tiny mass that it is not counted toward the atom's atomic mass number.
What is an electron?
The most electronegative element on the periodic table.
What is Fluorine?
In a Lewis structure, a single line drawn between two chemical symbols represents this many shared electrons.
What is 2?
The shielding effect on valence electrons stays constant on a graph across a single period because the number of occupied energy levels does not change.
What are inner energy levels (or electron shells)?
Ionic compounds conduct electricity only when they are in these two physical states or forms.
What is liquid (molten) or dissolved in water?
The scientist who discovered the nucleus using the famous Gold Foil Experiment.
Who is Ernest Rutherford?
This property—the energy released when a neutral atom gains an electron—generally becomes more negative across a period.
What is Electron Affinity?
The correct chemical formula for Magnesium Nitrate.
What is Mg(NO3)2?
