Metallic bonds are responsible for many properties of metals, such as conductivity. Why is this possible?(1 point)

Question

Responses:
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.
An attraction between a positive charge and a negative charge is created.

Answer 1

The correct response is:

The bonds can shift because valence electrons are held loosely and move freely.

This characteristic of metallic bonds allows for the delocalization of electrons, which contributes to the conductivity of metals.

Answer 2

Between which types of elements do ionic bonds occur, and how do electrons act within the bond?(1 point)
Responses:
metals and metals, electrons freely moving
metals and nonmetals, electrons transferred
nonmetals and metals, electrons shared
nonmetals and nonmetals, electrons shared

Answer 3

The correct response is:

metals and nonmetals, electrons transferred.

In ionic bonds, electrons are transferred from the metal (which loses electrons) to the nonmetal (which gains electrons).

Answer 4

Which kind of bond would occur between sodium (Na, Group IA) and chlorine (Cl, Group VIIA)?(1 point)
Responses:
covalent
metallic
ionic
no bond

Answer 5

The correct response is:

ionic.

Sodium (Na) is a metal that loses an electron to achieve a stable electron configuration, while chlorine (Cl) is a nonmetal that gains an electron. This transfer of electrons forms an ionic bond.

Answer 6

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)
Responses:
three metallic bonds
two ionic bonds
four covalent bonds
one covalent bond

Answer 7

The correct response is:

two ionic bonds.

However, this may be misleading in its wording. The correct statement should actually be that carbon dioxide (CO₂) consists of two covalent bonds formed between carbon and each oxygen atom (as carbon shares electrons with each of the two oxygen atoms). It's important to note that carbon forms double covalent bonds with each oxygen, so in total, CO₂ has two double covalent bonds (or four covalent bonds when counting the shared pairs of electrons).

Thus, if choosing from the available answers, the best fit would actually be:

four covalent bonds.

But do keep in mind that the actual formation in CO₂ involves two double covalent bonds (or four bonding interactions) between carbon and oxygen.
