Chemical Bonding

Question 1

What information on the periodic table is used to complete electron dot diagrams?

Revolt · Accepted Answer

The number before the A at the top of a column shows how many dots to draw in the diagram.

Question 2

Which atom is most likely to form a metallic bond?

Revolt · Accepted Answer

aluminum (Al)

Question 3

When sodium atoms (Na) and chlorine atoms (Cl) join to make sodium chloride, or table salt, they form an ionic bond. Using this information, which pair of elements is most likely to form an ionic bond?

Revolt · Accepted Answer

potassium (K) and fluorine (F)

Question 4

Which pairs of elements do not have to satisfy the octet rule for stability?

Revolt · Accepted Answer

helium (He) and hydrogen (H)

Question 5

The electron dot diagram shows the arrangement of dots without identifying the element.

Revolt · Accepted Answer

tellurium (Te)

Question 6

The diagram shows an electron shell model of a sodium atom.

Revolt · Accepted Answer

The third shell would be empty so that the eight electrons in the second level would be outermost after the atom loses one electron.

Question 7

The electron dot diagram shows the arrangement of dots without identifying the element.

Revolt · Accepted Answer

arsenic (As)

Question 8

Magnesium acts similar to sodium when forming an ionic bond in terms of losing or gaining electrons. What is the most likely way in which an atom of magnesium (Mg) will satisfy the octet rule when it forms bonds?

Revolt · Accepted Answer

by losing two electrons

Question 9

Hee Sun drew an electron dot diagram of a silicon atom as shown.

Revolt · Accepted Answer

The same number of dots would appear in the diagram for carbon.

Question 10

Based on the location of nitrogen (N) on the periodic table, how many additional electrons does a nitrogen atom need in its valence shell to satisfy the octet rule when it forms bonds?

Revolt · Accepted Answer

three
