HONORS- Chemistry 2nd CBA REVIEW-- 24/25

Front

What is a Halogen?

Back

Halogens are a group of elements in Group 17 of the periodic table, known for their reactivity and tendency to form salts with metals. Examples include Fluorine, Chlorine, Bromine, Iodine, and Astatine.

Front

What happens if a proton is added or removed from an atom?

Back

The atom becomes a different element, as the number of protons defines the identity of the element.

Front

Who created the Periodic Table and arranged elements in increasing atomic mass?

Back

Dmitri Mendeleev is credited with creating the first widely recognized periodic table.

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

What do nonmetals typically do when they form ionic bonds?

Back

Nonmetals typically gain electrons when they form ionic bonds.

Front

What is the difference between an isotope and an element?

Back

An isotope is a variant of an element that has the same number of protons but a different number of neutrons.

Front

What is the significance of the periodic table?

Back

The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties.

Front

What are the properties of metals?

Back

Metals are typically shiny, malleable, ductile, and good conductors of heat and electricity.

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 the role of electrons in chemical bonding?

Back

Electrons, particularly valence electrons, are involved in forming chemical bonds between atoms.
