States of matter
in what state of matter do molecules vibrate in place?
Solid
who is the scientist who proposed the nuclear model after the gold foil experiment?
Thomas Rutherford
This trend increases across a period and decreases down a group.
Electronegativity
Bond formed by the transfer of electrons
Ionic bond
The number in front of a compound that balances an equation
Coefficient
What state of matter would a star be considered?
Plasma
The particle discovered by J.J. Thomson in experiments.
Electrons
Element with the highest ionization energy on the periodic table.
Fluorine
Type of bond where electrons are shared unequally.
Polar covalent bond
Balance: H2 + O2 -> H2O
It equals......2H2 + O2 -> 2H2O
What state of matter would water be?
Liquid
This persons atomic model included electrons in fixed energy levels.
Bhor
Moving down a group, atomic radius does this. (HINT: it increases or decreases)
Increases
The force between molecules, like hydrogen bonding
Intermolecular force
what type of reaction is this?: AB -> A + B
Decomposition reaction
What is melting?
Ancient Greek philosopher who first proposed the idea of indivisible particles.
Democritus
The energy required to remove an electron from an atom
Ionization
Bond type found in metals, involving a sea of electrons.
Metallic bonding
The law that requires equations to be balanced
Law of conservation of mass
Why is a rock considered a solid?
It has a definite shape and volume
The experiment that led to the discovery of the nucleus.
Gold foil experiment
This element has the largest atomic radius.
Francium
Molecule like H2O has this due to uneven electron distribution (Why is this???)
Because it is a polar bond
Balance: CH₄ + O₂ -> CO₂ + H₂O
It equals........CH₄ + 2O₂ -> CO₂ + 2H₂O
