Chapter 11
If 1.0 gram of antimatter meets with 4.0 grams of matter, the energy released would correspond to the energy equivalent of
2 grams
The atoms in isotopes of a particular element have different numbers of
Neutrons
The shell model of the atom views electrons as occupying
Shells
Which of these elements has the greatest mass
Uranium
Which of these elements has the greatest number of electrons
Uranium
If you add or subtract a proton to or from the nucleus of an atom, you produce
a completely different atom
Molecules are composed o
atoms
An element is a substance consisting of
atoms of the same kind
The reason you don't fall between the atoms in the floor you stand on involves
electrical forces
Smallest mass
electron
The size of an atom is mostly determined by its
electrons
compound is comppsed of
in definite proportions
The classic periodic table
lists the known elements
Isotopes a give element differ in
mass number
Brownian motions has to do with the
random motion of atoms and molecules
Atoms combine to form molecules by way of
shared or exchanged electrons
Investigation of atoms sequenced along each horizontal row (period) of the periodic table shows that atoms decrease in
size
Compared with the wavelength of visible light atoms are
smaller
The atomic number of an atom is defined by
the number of protons
It is correct to say that atoms that make up your body
were formed in ancient stars were previously a part of your neighbor's bodies are in motion at all times
