About This Board

A high-school chemistry review covering periodic table organization, trends, bonding, ions, and element families. This is a Grades 9–12 Science review game in a Jeopardy-style format: a teacher puts the board on one screen, teams pick clues by point value, and the class answers out loud — no student devices or accounts needed. Categories: Table Basics, Families, Periodic Trends, Ions & Bonding, Element Clues.

Table Basics

$100 — The horizontal rows of the periodic table are called these.
periods
$200 — The vertical columns of the periodic table are called these.
groups
$300 — Elements are arranged primarily by increasing this number.
atomic number
$400 — The atomic number equals the number of these in the nucleus.
protons
$500 — An element's chemical symbol is usually one or two of these.
letters

Families

$100 — Group 1 elements are known as these metals.
alkali metals
$200 — Group 17 elements are called these.
halogens
$300 — Group 18 elements are known as these gases.
noble gases
$400 — Elements in the center d-block are generally called these.
transition metals
$500 — Hydrogen is unusual because it sits above Group 1 but is this type of element.
a nonmetal

Periodic Trends

$100 — Atomic radius generally increases as you move this direction down a group.
downward
$200 — Atomic radius generally decreases moving left to right because effective nuclear charge does this.
increases
$300 — Ionization energy generally increases moving this way across a period.
left to right
$400 — Electronegativity is highest near this element.
fluorine
$500 — Metallic character generally increases toward this corner of the periodic table.
the bottom left

Ions & Bonding

$100 — When an atom loses electrons, it becomes this positively charged ion.
a cation
$200 — When an atom gains electrons, it becomes this negatively charged ion.
an anion
$300 — A bond formed by electron transfer is this type.
an ionic bond
$400 — A bond formed by sharing electrons is this type.
a covalent bond
$500 — NaCl is held together primarily by this type of attraction.
ionic attraction

Element Clues

$100 — This element has atomic number 6 and forms the backbone of organic molecules.
carbon
$200 — This element has symbol Fe.
iron
$300 — This noble gas has atomic number 10.
neon
$400 — This halogen is commonly added to toothpaste compounds.
fluorine — Element Clues
$500 — This metal is liquid near room temperature and has symbol Hg.
mercury — Element Clues
