Out of Be, Mg, and Ca, which element would you expect to have the STRONGEST pull on its electrons? Why?

Be (Beryllium). Include 1 of the following: 1. Because it has the fewest electron rings and the distance is the smallest. 2. Highest electronegativity.

Name the 2 factors that affect the strength of attractive force in atoms.

Distance of the electrons from the nucleus and the number of protons

Out of Li, Be, and B, which element would you expect to have the WEAKEST pull on its electrons? Why?

Li (Lithium). Include 1 of the following: 1. Because it has the least protons of these. OR 2. Because B has the largest atomic radius of these.

Out of Be, Mg, and Ca, which element would you expect to have the LARGEST atomic radius? Why?

Ca (Calcium). Include 1 of the following: 1. Because it has the most electron rings / most electrons. 2. Lowest electronegativity.

Elements in the same ______ have the same number of VALENCE electrons.

Group

Name 2 elements that would have similar properties to chlorine. Why are these similar?

Answers include: Fluorine, Bromine, Iodine, Astatine, or Tennessine because these are in the same group as chlorine.

Out of Li, Be, and B, which element would you expect to have the LARGEST atomic radius? Why?

Li (Lithium). Because it has the least protons of these, which decreases how much it pulls on its electrons.

Name a group of metals that is very reactive on the periodic table. Explain why this group is so reactive?

Alkali Metals OR Alkaline Earth Metals. In order to become stable, these metals react violently while donating their electrons.

Out of Be, Mg, and Ca, which element would you expect to have the SMALLEST atomic radius? Why?

Be (Beryllium). Include 1 of the following: 1. Because it has the least electron rings / least electrons. 2. Highest electronegativity.

How many VALENCE electrons would a boron atom have?

3

How many VALENCE electrons would a lithium atom have?

1

Out of Be, Mg, and Ca, which element would you expect to have the WEAKEST pull on its electrons? Why?

Ca (Calcium). Include 1 of the following: 1. Because it has the most electron rings and the distance is the largest. 2. Lowest electronegativity.

Out of Li, Be, and B, which element would you expect to have the STRONGEST pull on its electrons? Why?

B (Boron). Include 1 of the following: 1. Because it has the most protons of these. OR 2. Because B has the smallest atomic radius of these.

How many VALENCE electrons would a calcium atom have?

2

How many CORE electrons would a beryllium atom have?

2

With the information provided, would you expect atom A, B, or C to have the strongest pull on its electrons? Why?

C because it has the most protons.

Which group on the periodic table contains all very unreactive elements? Why are they so unreactive?

The Noble Gases. These are unreactive because they are already stable with a full valence shell of electrons and so they don't need to react with other atoms.

Name a group of nonmetals that is very reactive on the periodic table. Explain why this group is so reactive?

The Halogens. In order to become stable, these nonmetals react vigorously while trying to take more electrons from other atoms.

With the information provided, would you expect atom A, B, or C to have the largest atomic radius? Why?

A, because it has the fewest protons, so it pulls its electrons the weaker than atoms B or C.

How many CORE electrons would a magnesium atom have?

10

Elements in the same ______ have the same number of CORE electrons.

Period

Out of Li, Be, and B, which element would you expect to have the SMALLEST atomic radius? Why?

B (Boron). Because it has the most protons of these, which increases how much it pulls on its electrons.
