Atoms
This tiny particle with a negative charge moves around the nucleus of an atom.
What is an Electron
This chart organizes all known chemical elements by increasing atomic number and repeating chemical properties
What is the periodic table
This type of chemical bond forms when atoms share pairs of electrons.
What is a covalent bond
This type of solution tastes sour and turns blue litmus paper red.
What is an acid
This common base is used in baking and has the chemical formula NaHCO₃.
What is baking soda
This positively charged particle found in the nucleus determines the atomic number of an element.
What is a proton
Elements in the same vertical column of the periodic table are called this.
What are groups
This type of bond forms when one atom transfers electrons to another, creating positively and negatively charged ions.
What is an ionic bond
This type of solution tastes bitter, feels slippery, and turns red litmus paper blue.
What is a base
The horizontal rows of the periodic table are called this.
What are periods
This neutral particle in the nucleus helps add mass to an atom but does not affect its charge.
What is a neutron
This number, equal to the number of protons in an atom, determines an element’s position on the periodic table.
What is the atomic number
The outermost electrons of an atom that participate in bonding.
What are valence electrons
This scale ranges from 0 to 14 and is used to measure how acidic or basic a solution is.
What is the pH scale
A solution with a pH of 1 is considered this on the pH scale.
What is strongly acidic
Atoms of the same element that have different numbers of neutrons are known by this term.
What are isotopes
These elements are found along the zigzag line of the periodic table and have properties of both metals and nonmetals.
What are metalloids
Atoms try to have this number of electrons in their outer shell.
What is 8
Acids release this particle into water.
What is a hydrogen ion (H+)
This element, atomic number 79, is highly valued for jewelry and electronics.
What is gold
The total number of protons and neutrons in an atom’s nucleus is known by this term.
What is the mass number
This region of the periodic table contains elements that are typically shiny, good conductors of heat and electricity, and malleable.
What are metals
Ionic bonds typically form between these two types of elements.
What are nonmetals and metals
Bases release this particle into water.
What is a hydroxide ion (OH-)
Known as the “king of chemicals,” this element forms compounds with almost every other element.
What is carbon
