Bonds
This bond is formed between a metal and a non-metal
What is an ionic bond?
This group contains soft, silvered-colored solids at room temperature, which react violently with water
What are alkali metals?
This scientist developed the Atomic Theory
Who is John Dalton?
This rule states that when atoms combine, they tend to achieve 8 valence electrons
What is the Octet Rule?
This is the percentage of a given isotope in a sample of an element
What is isotopic abundance?
This bond is formed between two non-metals. The atoms gain partial charges
What is a covalent bond?
This group contains gases at room temperature that are highly unreactive
What are noble gases?
This scientist discovered the electron.
Who is J.J Thomson
This is a charged entity that forms when an atom gains or loses one or more electrons
What is an ion?
This is an isotope that gives off radiation as it decays
What is a radioisotope?
This bond is formed between two atoms of similar electronegativity. Usually forms homonuclear diatomic atoms
What is a non-polar covalent bond?
This group contains elements at all three states at room temperature, which are extremely reactive
What are the halogens?
Through his famous "gold foil experiments", this scientist discovered the nucleus and the proton
Who was Ernest Rutherford?
This is a positively charged ion
What is a cation?
This is the weighted average of the masses of all the naturally occurring isotopes in an element
What is average atomic mass?
These are the electrons that are involved in bonding
What are valence electrons?
These elements which look like a "staircase" exhibit both metallic and non-metallic properties
What are the metalloids?
This is a negatively charged ion
What is an anion?
Alpha, beta, and gamma
What are the three types of radioactive decay?
What is a metal bond?
These elements, located in the middle of the periodic table, are strong, hard metals with high-melting points
What are the transition metals?
This Greek philosopher named the atom from the word atomos, meaning "indivisible"
Who was Democritus?
This is an ion made up of more than one atom
What is a polyatomic ion?
This is a version of an element with the same number of protons, but a different number of neutrons
What is an isotope?
