Atomic Structure
Three parts of an atom
What are protons, neutrons, and electrons?
A vertical column on the periodic table is sometimes called this
What is a group?
The electron configuration for hydrogen
What is 1s1 ?
This type of bond is formed by the transfer of electrons. It is the attraction of oppositely charged ions

This molecule has two DIFFERENT elements bound together
What is a compound?
The electron configuration for Lithium
What is 1s22s1 ?
This bond is formed from electrons being shared between two atoms
What is a covalent bond?
What is a metalloid?
This is the term for an atom that has lost or gained an electron
What is an ion?
The number of valence electrons in oxygen
What is 6?
The electron configuration for nitrogen
What is 1s22s22p3 ?
This type of bond means that the electrons are unequally shared
What is a polar covalent bond?
Which of these is more electronegative: carbon or oxygen?

What is 2?
An electron has been promoted from a lower energy level to a higher energy level- we call this an ____________________________
What is an excited state?
This rule for writing electron configurations states that electrons must occupy the lowest energy orbitals first
What is the aufbau principle?
This rule states that atoms are most stable when they have 8 valence electrons (or a full valence shell)
What is the octet rule?
This periodic trend describes "how much an atom wants to gain an electron"
