7.03: Ionic Bonding

Multiple Choice

An element's identity is determined by the number of

• electrons.
• protons.
• neutrons.
• valence.

Multiple Choice

Which subatomic particle has a negative charge in the atom?

• proton
• neutron
• electron
• quark

Multiple Choice

Which is an electron?

• A
• B
• C

SWBAT: I can discuss how ionic bonds form between metals and nonmetals.

Vocabulary

ion: a charged atom

cation: a positively charged atom that has lost an electron(s)

anion: a negatively charged atom that has gained an electron(s)

ionization energy: the amount of energy required for an atom to lose an electron​

Multiple Choice

What is a cation's charge?

• positive

• negative

• neutral

• depends on the element

Multiple Choice

Is potassium a cation or an anion?

• cation

• anion

Multiple Choice

What is an anion's charge?

• positive

• negative

• neutral

• depends on the element's charge

Multiple Choice

Is the ion sodium a cation or an anion?

• cation

• anion

Ionization Energy

Ionization energy: the amount of energy required for an electron to be removed from an atom to form an ion.

• ​Periodic trend: ionization energy increases as you move left to right and down to up the periodic table​

Multiple Choice

What is ionization energy?

• Energy needed to destroy an atom
• Energy required to remove an electron
• Energy needed to split an electron
• Energy required to add an electron

Multiple Choice

Which element has the greater ionization energy?

• Magnesium (Mg)

• Phosphorus (P)

Multiple Choice

ionic bonds form between

• a metal and nonmetal

• two nonmetals

• two metals

Multiple Choice

What is the total charge of an ionic compound?

• positive

• negative

• neutral
