Unit 5- Atomic Structure and Periodic Table Exam Review 2

Front

What is the atomic radius trend in the periodic table?

Back

Atomic radius decreases as you move from left to right across a period and increases as you move down a group.

Front

Which element has the smallest atomic radius?

Back

Fluorine has the smallest atomic radius among the given options.

Front

What are subatomic particles?

Back

Subatomic particles are the particles that make up an atom, including protons, neutrons, and electrons.

Front

What is the charge and mass of protons?

Back

Protons have a positive charge and a mass of approximately 1 atomic mass unit (amu).

Front

What is the charge and mass of neutrons?

Back

Neutrons are neutral particles with a mass of approximately 1 atomic mass unit (amu).

Front

What is the charge and mass of electrons?

Back

Electrons have a negative charge and a very small mass compared to protons and neutrons.

Front

What is a compound?

Back

A compound is a substance formed when two or more different kinds of atoms chemically combine.

Front

What happens to ionization energy as you move up and to the right on the periodic table?

Back

Ionization energy increases as you move up and to the right on the periodic table.

Front

What is electronegativity?

Back

Electronegativity is the tendency of an atom to attract electrons in a chemical bond.

Front

What are isotopes?

Back

Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons.
