Open Scied 7.4

In the modern Periodic Table, elements are arranged

• according to atomic mass.

• according to atomic number.

• in alphabetical order.

• according to the number of neutrons in their nuclei.

The atomic number tells you what?  READ THE ANSWERS CAREFULLY

• only the number of electrons

•  only the number of protons

• only the number of neutrons

• the number of both electrons and protons in an atom.

What does the atomic mass tell you? 

• Basically,the number of electrons and protons

• The number of neutrons

• Basically, the number of protons and neutrons

• The number of protons.

The atoms we study in 6th grade are neutral, which means they have the same number of

• protons and electrons

• protons and neutrons

• electrons and neutrons

• Top predator

• Carnivore

• Herbivore

• Producers
