PS Unit 4 Mid Review: through bonds

Front

What is a property of metals?

Back

Metals are malleable, meaning they can be hammered or pressed into shapes without breaking.

Front

What subatomic particle has a negative charge?

Back

The electron is the subatomic particle with a negative charge.

Front

Which type of element loses its valence electrons easily?

Back

Metals lose their valence electrons easily and become positively charged when forming compounds.

Front

What type of bond results from the sharing of electrons between two nonmetal elements?

Back

A covalent bond results from the sharing of electrons between two nonmetal elements.

Front

What is the difference between a mixture and a pure substance?

Back

A mixture contains two or more substances that are not chemically combined, while a pure substance has a uniform and definite composition.

Front

Define malleability in metals.

Back

Malleability is the ability of a metal to be deformed under compressive stress, allowing it to be shaped into thin sheets.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions.

Front

What is a covalent bond?

Back

A covalent bond is formed when two nonmetal atoms share one or more pairs of electrons.

Front

What are nonmetals?

Back

Nonmetals are elements that typically lack the properties of metals and can gain electrons to form negative ions.

Front

What is a metalloid?

Back

Metalloids are elements that have properties intermediate between metals and nonmetals.
