Ions Formed From Representative Elements

What defines the characteristic of noble gases that makes them unreactive?

• Low electron affinity

• Complete outer shells

• High ionization energy

• Easy electron loss

What is the main factor that determines whether an element becomes a cation or anion?

• Group number in the periodic table

• Number of protons

• Atomic weight

• Electron configuration

Which group of elements tends to readily lose valence electrons in bond formation?

• Halogens

• Alkali metals

• Noble gases

• Alkaline earth metals

What is the outcome when an element gains or loses electrons?

• It becomes inert

• It forms a bond

• It becomes an ion

• It becomes a metalloid

What charge is typically observed for Group 3A elements when they form ions?

• +1

• +2

• +3

• -1

What defines an anion?

• It gains electrons

• It loses electrons

• It becomes inert

• It has a positive charge

Which type of elements generally has a higher electron affinity?

• Metals

• Noble gases

• Nonmetals

• Metalloids

What is the role of ionization energy in the formation of ions?

• Higher ionization energy leads to easier ion formation

• Lower ionization energy leads to easier ion formation

• Ionization energy is unrelated to ion formation

• Ionization energy decreases with electron affinity

Which statement best describes the ionization energy trend across the periodic table?

• It increases from left to right and decreases from top to bottom

• It decreases from left to right and increases from top to bottom

• It remains constant across the periodic table

• It varies randomly across periods and groups

How do nonmetals typically achieve stability in bond formation?

• By losing electrons

• By gaining electrons

• By forming covalent bonds

• By ionizing metals
