Which element has the smaller atomic radius: potassium (K) or bromine (Br)?

• potassium (K)
• bromine (Br)

In the modern periodic table elements are arranged by:

• atomic mass
• atomic number
• valence electrons
• number of isotopes

Which of these is a property of metals?

• It's malleable
• It can't conduct electricity
• They are used in food
• It's very brittle

What is a cation's charge?

• positive

• negative

• neutral

• depends on the element

What is an anion's charge?

• positive

• negative

• neutral

• depends on the element's charge
