Chapter 2 Flashcards
(24 cards)
The mass of an atom is primarily due to the
Nucleus
Protons and neutrons equal the
Atomic Mass
The earliest atomic theory based on the arrangement of the solar system was attributed to
Rutherford
The L shell can hold… electrons
8
What is the formula for finding electron shell
2n^2
Atoms with same atomic number but different atomic mass number are
Isotopes
Plum pudding model is associated with
Thompson
8 electrons is the max for the outermost shell
True
Atoms in the same group have the same number of
Electrons in the outermost shell
N shell can hold
32 electrons
Ionic bond results in a electrically charged atom
False.
Atoms with the same amount of neutrons but different amount of protons are
Isotones
Atoms with same atomic mass number but different amount of protons are
Isobars
John Dalton theorized
Elements form compounds, atoms are unique to each element in size and mass, a chemical reaction happens when they are rearranged.
Most commonly known modern atomic theory is associated with
Bohr
Atoms with the same level of protons and neutrons but different energy levels are
Isomers
Discovery of electron is associated with
Thompson
Earliest atomic theory is associated with
Leucippitus
Atoms in each period have the same amount of electron shells
True
Formed when two atoms share electrons. Orbiting each others outermost shell
Covalent bonds
Atoms that are bonded together because of their opposite charge are known as
Ionic bonds
Each element has an unchangeable number of protons
True
Elements at the top of the periodic table of Elements are the most complex
False
