Atom Flashcards
Location where electrons are found
Electron cloud
It is the central part of an atom
Nucleus
The particles of atoms are made of what?
Fermions and bosons
What do you call fermions and bosons?
Elementary particles
What are the two families of fermions?
Quarks and leptons
They are the fundamental forces (force carriers)
Bosons
Where does bosons come from?
Big bang
It causes mass.
Higgs
It causes the strong force
Gluon
It is an elementary particle and a fundamental constituent of matter
Quark
Quarks combine to form composit particles called what?
Hadrons
What are the six flavours of quarks?
Up, down,charm, strange, top and bottom
What is proton made up of?
2 up + 1 down and held together by gluons = proton
A neutron is made up of what?
1 up + 2 downs = neutron
It is an elementary, spin -1/2 particle that does not undergo strong interactions.
Lepton
It governs nearly all of chemistry as it is found in atoms and is directly tied to all chemical properties.
Electron
How are electrons attracted to the protons in the nucleus?
By the photon (electromagnetic force)
The atomic number indicates what?
Number of protons
It tells us what element we are reffering to
Number of protons
It tells us about the element’s isotope
Number of neutrons
Elements that have similar number of protons and different number of neutrons.
Isotope
It tels us about the element’s charge
Number of electrons
It has the same number of protons and electrons.
Neutrol atom
Different number of protons and electrons is called what?
Ion
Positive charged ions
Cations
Negative charged ions
Anions
Where are electrons distributes?
Orbitals
He dismissed the idea of electrons oebiting the nucleus
Schrödinger
It is the distribution of electrons kf an atom in atomic orbitals
Electron configuration
It is a pure substance consisting two or more atoms
Compound
Involves transfer of electons between two or more atoms
Ionic bond
Involves the sharing of electrons between two or more atoms
Covalent bond
Metal lose electrons because they are ____________.
Positive
Is a anion a metal or nonmetal?
Nonmetal
What rule includes 8 electrons to make it stable?
Octet rule
Nonmetals gain electrons because they are _________.
Negative
Is cation a metal or a nonmetal?
Metal
