Chemical Bonding

What type of bond will form between a metal and a nonmetal?

An ionic bond will form

What does the octet rule state that explains why atoms bond?

An atom bonds to have eight valence electrons to become stable.

Fluorine (F) and bromine (Br) are in the same group on the periodic table. How do atoms of these elements compare when they form bonds?

Both a fluorine atom and a bromine atom gain one electron, and both atoms become stable.

What type of bond will form between a nonmetal and a nonmetal?

Covalent bond

An atom of lithium (Li) forms an ionic bond with an atom of chlorine (Cl) to form lithium chloride. How are the valence electrons of these atoms rearranged to form this bond?

Electrons are transferred from the lithium atom to the chlorine atom.

Helium (He) and neon (Ne) are elements in Group 8A of the periodic table. How do the electron dot diagrams of these elements compare?

The electron dot diagram of helium has six fewer electrons than the electron dot diagram of neon.

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

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

Hee Sun drew an electron dot diagram of a silicon atom as shown. In addition to changing the symbol to C, how would this diagram compare with an electron dot diagram of a carbon atom (C)?

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

The diagram shows an electron shell model of a sodium atom. How would the model change as the atom forms bonds?

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

The electron dot diagram shows the arrangement of dots without identifying the element. Which element's symbol could replace the question mark in the diagram?

arsenic (As)

The type of chemical bond that involves the transfer of electrons between atoms is a(n) _ bond.

ionic

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?

potassium (K) and fluorine (F)

The electron dot diagram shows the arrangement of dots without identifying the element. Which element's symbol could replace the question mark in the diagram?

tellurium (Te)

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?

three
