Chemistry First Semester Final Practice Test - Period 1

Front

What is a metal?

Back

A metal is a type of element that is typically hard, shiny, malleable, ductile, and a good conductor of heat and electricity. Examples include iron, copper, and gold.

Front

What are the properties of metals?

Back

Metals generally have high melting points, strong metallic bonds, are malleable, ductile, and good conductors of electricity and heat.

Front

What is electronegativity?

Back

Electronegativity is the tendency of an atom to attract electrons when chemically bonded to another atom.

Front

How do you calculate the mass number of an atom?

Back

The mass number is calculated by adding the number of protons and neutrons in the nucleus of an atom.

Front

What does the atomic number represent?

Back

The atomic number of an element represents the number of protons in the nucleus of an atom.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state.

Front

What is the difference between metals and nonmetals?

Back

Metals are typically shiny, malleable, and good conductors, while nonmetals are usually dull, brittle, and poor conductors.

Front

What is a metalloid?

Back

Metalloids are elements that have properties of both metals and nonmetals. Examples include silicon and germanium.

Front

What is a noble gas?

Back

Noble gases are a group of elements in Group 18 of the periodic table that are colorless, odorless, and inert under standard conditions. Examples include helium, neon, and argon.

Front

What is the significance of high melting points in metals?

Back

High melting points indicate strong metallic bonds, which require a lot of energy to break.
