Exam 2: Structure of the Atom

For the chemical element sodium (²²₁₁Na),the atomic number is:

The word atom is derived from the Greek word atomos,meaning:

The number of protons and neutrons in the atom's nucleus is the:

A positive ion is:

In the early 1800s English chemist John Dalton theorized that:

The three fundamental particles of the atom are the:

Atoms with the same number of neutrons but different number of protons are:

When the bond between two atoms is due to their sharing an outer-shell electron,this is called a:

If an atom has more electrons than protons it will:

The number of protons in an atom's nucleus is reflected in its:

Atoms in each period have the same number of:

The N shell can hold _______ electrons.

The electron binding energy depends on:

The periodic table of elements classifies by period and group.The period is the:

The mass of an atom is primarily due to the mass of the:

Each electron shell has a specific limit to the amounts of electrons it can hold.

The "plum pudding model" is associated with:

The earliest atomic theory based on the arrangement of the solar system is attributed to:

If an atom has the same number of electrons and protons it will:

The atoms of the elements at the top of the periodic table of elements are the most complex.
