Physics 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.
Which of the following has the smallest mass?
Electron
Which of these elements has atoms of the greatest mass?
Uranium
If you add or subtract a proton to or from the nucleus of an atom, you produce
a completely different atom.
An element is a substance consisting of
atoms of the same kind.
Molecules are composed of
atoms.
The reason you don't fall between the atoms in the floor you stand on involves
electrical forces.
The size of an atom is mostly determined by the space occupied by its
electrons.
A compound is composed of different kinds of atoms
in definite proportions.
The classic periodic table
lists the known elements.
Isotopes of a given element differ in
mass number.
The atoms in isotopes of a particular element have different numbers of
neutrons.
The atomic number of an atom is defined in terms of its number of
protons.
Brownian motion has to do with the
random motions of atoms and molecules.
Atoms combine to form molecules by way of
shared or exchanged electrons.
The shell model of the atom views electrons as occupying
shells
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.
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. All of these.
