A) Metallic bonds are responsible for many properties of metals, such as conductivity. Why is this
possible? (1 point)
An attraction between a positive charge and a negative charge is created.
Metals have low electronegativity, so they are conductive because they pass charges easily.
The bonds can shift because valence electrons are held loosely and move freely.
Two metals bonded together are going to be more conductive than a metal bonded with a nonmetal.
A) Between which types of elements do ionic bonds occur, and how do electrons act within the bond?
(1 point)
nonmetals and metals, electrons shared
metals and metals, electrons freely moving
nonmetals and nonmetals, electrons shared
metals and nonmetals, electrons transferred
A) Which kind of bond would occur between sodium (Na, Group IA) and chlorine (Cl, Group VIIA)?
(1 point)
no bond
ionic
metallic
covalent
Question 4
A) Which type of bond and how many bonds would occur as carbon dioxide (CO2) is formed from
carbon in Group IVA and oxygen in Group VIA? (1 point)
one covalent bond
four covalent bonds
three metallic bonds
two ionic bonds
Question 5
A)
Use the periodic table to answer the question.

According to VSEPR theory, how should the molecular shape of be classified?
(1 point)
AsF3
linear, because the arsenic atom forms bonds with only one other type of atom
tetrahedral, because the arsenic atom forms bonds with the three atoms and the lone pair
trigonal pyramidal, because the arsenic atom forms three single covalent bonds and has one lone pair
trigonal planar, because the arsenic atom forms three single covalent bonds and has no lone pairs

Here are the answers to your questions based on the provided choices:
**Question 1:**
A) Metallic bonds are responsible for many properties of metals, such as conductivity. Why is this possible?
**Answer:** The bonds can shift because valence electrons are held loosely and move freely.
**Question 2:**
A) Between which types of elements do ionic bonds occur, and how do electrons act within the bond?
**Answer:** metals and nonmetals, electrons transferred.
**Question 3:**
A) Which kind of bond would occur between sodium (Na, Group IA) and chlorine (Cl, Group VIIA)?
**Answer:** ionic.
**Question 4:**
A) Which type of bond and how many bonds would occur as carbon dioxide (CO2) is formed from carbon in Group IVA and oxygen in Group VIA?
**Answer:** two covalent bonds. (Note: CO2 actually has two double bonds, but if only counting the total number of bonds formed, two single bonds would be counted as one bond each.)
**Question 5:**
A) According to VSEPR theory, how should the molecular shape of AsF3 be classified?
**Answer:** trigonal pyramidal, because the arsenic atom forms three single covalent bonds and has one lone pair.
