Atoms and Elements

The chart that arranges elements by atomic number is:

• Atomic Number
• Metal
• Periodic Table
• Chart

If an element does NOT conduct electricity and is NOT shiny or malleable, it is a:

• Metal
• Nonmetal
• Gas
• Liquid

A NEGATIVE subatomic particle is:

• Electron
• Neutron
• Proton
• Metal

The smallest unit of an element that still has the properties of that element is:

• Proton
• Nonmetal
• Atomic number
• Atom

A substance that is generally shiny, can be bent, and often conducts heat and electricity is:

• Gas
• Nonmetal
• Metal
• Element

Which are the four types of matter?  

• Plasma, gas, liquid, solid
• Plasma, metal, nonmetal, element
• Gas, liquid, metal, atoms
• Liquid, ice, gas, atoms

A POSITIVE subatomic particle:

• Neutron
• Electron
• Atom
• Proton

What determines the properties of elements?

• Nonmetal
• Atomic number
• Periodic Table
• Electrons

Which statement does NOT describe the current  model of an atom?

• Atoms are mostly empty space
• The positive charge is concentrated in the nucleus
• Electrons are found in a "cloud" around the nucleus
• Electrons are embedded in a positively charged sphere

Which is the BEST reason that the periodic table is a useful tool?

• It shows a symbol for each element
• It arranges elements by atomic mass
• It groups metals on the right and nonmetals on the left
• It arranges elements with similar properties into columns
