Atoms
The smallest unit of an element that retains the chemical properties of that element.
What is an Atom?
A stable, negatively charged subatomic particle with almost no mass.
What is an electron?
H
What is the Chemical Symbol for Hydrogen?
A one or two-letter abbreviation for the element.
What is the Atomic Symbol?
Formed by the electrostatic attraction between oppositely charged ions (cations and anions).
What is an Ionic Bond?
Solid, liquid, gas
What are the phases of matter?
The region around an atom's nucleus where there is a high probability of finding an electron.
What is the electron orbital?
O
What is the Chemical Symbol for Oxygen?
The number of protons in the nucleus of an atom of that element.
What is a Atomic Number?
Formed by the sharing of electrons between atoms.
What is a Covalent Bond?
Three main subatomic particles of an atom.
What are protons, neutrons, and electrons?
The electrons in an atom's outermost shell located furthest from the nucleus, and they are electrons that participate in forming chemical bonds.
What are valance electrons?
Na
What is the Chemical Symbol for Sodium?
The average mass of an atom of the element. It's a weighted average of all the naturally occurring isotopes of that element.
What is the Atomic Mass?
Electrons are delocalized, meaning they are not associated with individual atoms but rather form a "sea" of electrons that can move freely throughout the structure.
What is a Metallic Bond?
Table used to organize atoms into periods and groups.
What is the periodic table?
Their full outermost electron shell makes this chemical group very stable and unreactive, according to the octet rule, as they have no tendency to gain or lose electrons to form chemical bonds.
What are Noble Gases?
Cl
What is the Chemical Symbol for Chlorine?
Identifies the number of electron shells an atom has, each one represents a new principal energy level for an atom's electrons.
What is a Row on the Periodic Table?
Dipole-dipole attraction involving a hydrogen atom bonded to a highly electronegative atom.
What is a Hydrogen Bond?
Short-range but powerful force holds protons and neutrons (nucleons) together in the nucleus
What is nuclear force?
These orbitals are most commonly associated with valence electrons, especially for main group elements.
Au
What is the Chemical Symbol for Gold?
Identifies elements with similar chemical properties and the same number of valence electrons.
What is a Group in the Periodic Table?
Weak intermolecular forces arising from temporary fluctuations in electron distribution.
What are Van der Walls Forces?
