Chapter 3 Lessons 1,2,3,4,5 Study Guide

What subatomic particles are located in the nucleus?

• Neutron & Electron

• Electron & Proton

• Proton & Neutron

What information can you get from an element's atomic number?

• The number of protons & neutrons in the nucleus

• The number of protons & electrons in the nucleus

• The number of electrons outside the nucleus

• The number of neutrons & electrons in the nucleus

How can an atom of an element be considered neutral?

• The number of protons & electrons have to be equal

• The number of neutrons & electrons have to be equal

• The number of atoms have to be equal

What is an isotope?

• Molecules with the same number of protons & different numbers of electrons

• Elements with the same number of protons & different numbers of electrons

• Atoms with the same number of protons & different numbers of electrons

• Matter with the same number of protons & different numbers of electrons

Where are the electrons located in an atom?

• Inside the nucleus

• Outside the nucleus, orbiting around it

• To the side of the nucleus, not moving

• Across the nucleus

What properties of the elements did Mendeleev study?

• melting point

• odor

• density

• atomic mass

• color

What information does the periodic table contain?

• chemical name

• atomic mass

• ductility

• atomic number

• chemical symbol

How do you identify the periods in the periodic table?

• Because it's arranged in rows & it contains a series of different elements

• Because it's arranged in columns & contains a series of similar elements.

How is the atomic mass of an element determined?

• By the average width of all the isotopes.

• By the average height of all the isotopes.

• By the average length of all the isotopes.

• By the average mass of all the isotopes.

How was Mendeleev's periodic table arranged?

• It was arranged in order of decreasing atomic mass

• It was arranged in order of increasing atomic mass

• It was arranged in order of decreasing atomic number

• It was arranged in order of increasing atomic number
