Semester 1 Review

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that occurs between a metal and a nonmetal, where electrons are transferred from one atom to another, resulting in the formation of charged ions.

Front

Which group of elements has the lowest ionization energies?

Back

Alkali Metals (Group 1) have the lowest ionization energies because they have a single electron in their outermost shell, which is easily removed.

Front

How many valence electrons does iodine have?

Back

Iodine has 7 valence electrons, which are located in its outermost electron shell.

Front

What type of bond is found between water molecules?

Back

Hydrogen bonds are the type of bond found between water molecules, which are weak attractions between the hydrogen atom of one water molecule and the oxygen atom of another.

Front

What are constraints in project management?

Back

Constraints are limitations or restrictions that affect the planning and execution of a project, such as time, budget, and resources.

Front

Define a covalent bond.

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons, typically occurring between nonmetals.

Front

What is the significance of valence electrons?

Back

Valence electrons are important because they determine how an atom can bond with other atoms, influencing the chemical properties of the element.

Front

What is the difference between polar and nonpolar covalent bonds?

Back

Polar covalent bonds occur when electrons are shared unequally between atoms, resulting in a molecule with a slight charge, while nonpolar covalent bonds involve equal sharing of electrons.

Front

What are alkali metals?

Back

Alkali metals are the elements found in Group 1 of the periodic table, characterized by having one electron in their outermost shell, making them highly reactive.

Front

What is ionization energy?

Back

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