Answer:
d. 8
Explanation:
Valence electrons of oxygen = 6
Valence electrons of hydrogen = 1
The total number of the valence electrons = 6 + 2(1) = 8
The Lewis structure is drawn in such a way that the octet of each atom and duet for the hydrogen in the molecule is complete.
In the water molecule,
<u>Oxygen has 2 bond pairs and two lone pairs which means that the total electrons in the valence shell is 8.</u>
I believe it would be A, frogs and spiders, because frogs and spiders both eat grasshoppers. But I cannot see the diagram it talks about, so it's harder to tell.
Answer:
A) Has properties of both metals and nonmetals - Barium.
B) Nonreactive gas - Neon.
C) Great conductor of heat and electricity - Boron.
D) Malleable and highly reactive - Potassium.
Explanation:

Correct Answer: <span>compound because the atoms of the elements are combined in a fixed proportion.
Reason:
A </span><span> chemical </span>compound is a chemical substance composed of element (of same or different type) that are bonded in a fixed proportion. Depending upon the type of element, bond can be ionic or covalent. In present case, <span>tetrachloromethane i.e. CCl4 has one 'C' atom that is covalently bonded to four 'Cl' atoms. </span>
The answer would be B: In the Earth’s atmosphere!.
Hope this helps,
