Periodic table trends

As you move down the periodic table atoms get bigger.  This is because ____________.

• The atoms have more mass.
• The atoms have more protons.
• The atoms have more energy levels
• The atoms have more nuetrons

Electronegativity is...

• how good an atom is at attracting electrons
• the ability of an atom to lose electrons
• the energy required to remove an electron from a specific atom
• how easy it is to make friends. 

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

A student drew a dot cross diagram with 7 valence electrons. Which of the following elements might have the student drawn?

• Cl (Chlorine)

• Ne (Neon)

• N (Nitrogen)

• Li (Lithium)

Elements in the same column of the periodic table always have the same # of _______ as one another.

• Protons
• Neutrons
• Electrons
• Valence Electrons

Rows on the period table are called _____ while columns are called _____.

• groups, families
• groups, periods
• periods, groups
• families, groups

The Modern Periodic Table of Elements is arranged by

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

Which is an alkali metal?

• Magnesium
• Iron
• Sodium
• Europium

Francium (Fr) has the lowest ionization energy in Group 1 because - 

• it has the smallest number of valence electrons
• it has the greatest atomic mass
• it has the greatest number of protons, so it attracts its electrons the strongest
• its 1 valence electron is very far from the nucleus, so little energy is needed to remove it

Which option correctly identifies the subatomic particle with its charge?

• Protons are negative

• Electrons are neutral

• Neutrons are negative

• Electrons are negative
