1. Since both carbon and oxygen are nonmetals, choice C is wrong.
QUESTION:
What type of bond is more likely between a carbon atom and an oxygen atom? A. ionic, B. covalent, C. metallic
Ionic bonding tends to occur between a metallic element and a nonmetallic element. Atoms of metallic elements tend to readily lose electrons and become positively charged, whereas atoms of nonmetallic element tend to gain electrons and become negatively charged.
Between two nonmetal atoms, electron sharing, “covalent bonding” is more likely to occur.
Among atoms of metallic element, electrons are loosely held and delocalized: “metallic bonding”
SCRIPT:
What type of bond is more likely between a carbon atom and an oxygen atom? A. ionic, B. covalent, C. metallic
PAUSE Ionic bonding tends to occur between a metallic element and a nonmetallic element.
Atoms of metallic elements tend to readily lose electrons and become positively charged,
whereas atoms of nonmetallic element tend to gain electrons and become negatively charged.
The ions would then be attracted to teach other and said to be involved in ionic bonding.
That’s not the case between carbon and oxygen. Carbon and oxygen are both nonmetallic elements.
CROSSOUT Choice A
Between two nonmetal atoms, electron sharing,… or covalent bonding is more likely to occur. Carbon and oxygen are both nonmetals. So the likely bond between these two atoms is covalent.
The correct answer is B.
Among atoms of metallic elements, electrons are loosely held and are more or less
free to move about among the atoms. We say that the electrons are delocalized among
the atoms. What we have among metallic atoms is called “metallic bonding”
Since both carbon and oxygen are nonmetals, choice C is wrong.

2. Here’s a periodic table to remind you where the metals and nonmetals are located in the periodic table.
The metallic elements are shown here highlighted in red.
The nonmetallic elements are highlighted in blue.
And the metalloids are not highlighted.
Here’s carbon
CLICK It’s a nonmetal
And here’s oxygen
CLICK It’s also a metal
