💡Periodic Trends
This property increases from left to right across a period due to increasing nuclear charge.
What is electronegativity?
The chemical symbol for gold.
What is Au?
These are the positively charged particles in an atom.
What are protons?
A bond formed by sharing electrons between atoms.
What is a covalent bond?
He created the first periodic table.
Who is Dmitri Mendeleev?
As you move down a group, this property increases because electrons occupy higher energy levels.
What is atomic radius?
The element named after the planet that’s known for its beautiful rings.
What is Saturnium? (Trick — none! The real one is Uranium after Uranus)
The center of the atom is called the ___.
What is the nucleus?
A bond formed when one atom donates an electron to another.
What is an ionic bond?
This number of elements are in a period (row) 2 of the periodic table.
What is 8?
This trend refers to how easily an atom loses an electron.
What is ionization energy?
This element’s name means “water-former.”
What is hydrogen?
This subatomic particle has almost no mass.
What is the electron?
Metals bonded together in a “sea of electrons” form this type of bond.
What is a metallic bond?
The only metal that is liquid at room temperature.
What is mercury?
Fluorine is the most ___ element on the periodic table.
What is electronegative?
The element with the symbol W comes from the German word wolfram.
What is tungsten?
The atomic number equals the number of these particles.
What are protons?
Water’s polar nature allows for this weak but important type of bond.
What is a hydrogen bond?
The element symbol Na stands for this common metal.
What is sodium?
This trend decreases as atomic radius increases.
What is electron affinity?
This element is named after Marie Curie’s homeland.
What is polonium?
Isotopes of an element differ in their number of ___.
What are neutrons?
The difference in this determines bond type (ionic, covalent, or polar covalent).
What is electronegativity?
The horizontal rows on the periodic table are called ___.
What are periods?
