Understanding Monatomic Ions

What determines the identity of an atom?

• The number of electrons

• The number of protons

• The number of neutrons

• The atomic mass

What happens to an atom when it loses electrons?

• It becomes a noble gas

• It becomes neutral

• It becomes an anion

• It becomes a cation

Which type of elements typically form anions?

• Non-metals

• Metalloids

• Noble gases

• Metals

What is the main goal of elements in the main group regarding their electron configuration?

• To have a full s sublevel

• To have a full d sublevel

• To achieve a noble gas configuration

• To have an odd number of electrons

What is the term used to describe elements with the same number of electrons as a noble gas?

• Isomeric

• Isobaric

• Isotopic

• Isoelectronic

How many electrons does nitrogen gain to become isoelectronic with neon?

• Four

• Three

• Two

• One

What charge does sulfur have when it gains two electrons?

• -2

• -1

• +2

• +1

Why are transition metals unique in terms of their ionic charges?

• They do not form ions

• They can have multiple positive charges

• They have a fixed positive charge

• They can only have a negative charge

How is the charge of a transition metal ion indicated in its name?

• By using a prefix

• By using a suffix

• By using a Greek letter

• By using a Roman numeral

Which of the following transition metals typically has only one positive charge?

• Iron

• Copper

• Silver

• Gold
