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
