Valence electrons are found on the outermost shell of an atom and determines the kind of bonds the atom can form.

When an atom has a large number of valence electrons, it is energetically more favorable for the atom to share electrons rather than to transfer electrons to another atom. Atoms with less valence electrons transfer electrons from one atom to another.

Since carbon is a member of group 14 and oxygen is a member of group 16, it follows that carbon can share four electrons with two oxygen atoms as shown in the structure O=C=O.

Carbon is always tetravalent in all its compounds. This means that one carbon atom must form four bonds. It follows that the carbon atom in CH4 forms four bonds with the four hydrogen atoms hence there are no bonds between hydrogen atoms in CH4.

H2O2 contains the peroxide (O-O) bond. It follows that its correct structure must be H–O–O–H.

Answer:

1. How many electrons does hydrogen need in order to have a full shell of valence electrons?...two

2. How do valence electrons impact the type of bonds an atom makes?...An atom wants a full outer shell of valence electrons, so it will either transfer or share electrons depending on what the other atom needs.

3.Use your knowledge of valence electrons and how they affect bonds to figure out how carbon (Group 14) and oxygen (Group 16) would be attached to one another. In carbon dioxide (CO2), how is the compound structured? (Use “–” to represent a single bond and “=” to represent a double bond.)...O=C=O

4. Methane’s chemical formula is CH4. Is there a bond between any of the hydrogen atoms? Why or why not?...No, there is not because carbon needs four bonds, so it bonds with each hydrogen atom; hydrogen only forms one bond.

5. In hydrogen peroxide (H2O2), which option best shows how the atoms are ordered?...H-O-O-H

How do strong southerly winds affect the vapor pressure?

dedylja [7]

Answer:

An increase

Explanation:

The strong southerly winds affect the vapor pressure by increasing it .

When the vapor pressure increases it means an increase in temperature and more evaporation occurs.

A decrease in the vapor pressure means a reduction in temperature with less amount of evaporation being involved

Metric conversions. Please help ASAP.

lesya692 [45]

Answer:

14. 13.2cg = 1.32dg

15. 3.8m = 0.0038km

16. 24.8L = 24800mL

17. 0.87kL = 870L

18. 26.01cm = 0.0002601km

19. 0.001hm = 10cm

Explanation:

14. 13.2/10 = 1.32

15. 38/1000 = 0.0038

16. 24.8(1000) = 24,800

17. 0.87(1000) = 870

18. 26.01/100000 = 0.0002601

19. 0.001hm(10000) = 10

An easy way to do these by yourself is to familiarize yourself with what each prefix means. Once you do this, you can multiply the value of the prefix when converting from a smaller unit of measurement to a larger one and divide the value of the prefix when converting from a large unit of measurement to a smaller one.

What type of chemical bond holds the na+ and cl- ions together in table salt?

fredd [130]

The bond between Na + and Cl- ions is an ionic bond

To achieve stability, atoms with low ionization energy such as Na atoms will release electrons and bind to atoms with high-affinity energy such as Cl atoms

$\boxed{\boxed{\bold{Further~explanation}}}$

Atoms have different stability. Unstable atomic atoms will try to form stable electron configurations like those of noble gases. Where noble gases have the number of outer electrons 2 or 8

The formation of electron configurations such as noble gases can be done by forming shared ions or electron pairs

Atoms with high ionization energy and atoms that are difficult to draw electrons will form bonds with shared electron pairs (electrons can be from one atom or two atoms attached)

In forming ions, atoms will release or attract electrons

Ion bonds occur because atoms that have low ionization energy (easily release electrons) form a + ion, and these electrons are bound by atoms that have large affinity energy (easily pulling electrons)

Generally, ionic bonds occur in metal and nonmetallic elements. Metal elements have low ionization energy and non-metallic elements have a high electron affinity

In Na atoms, to achieve stability, Na will release one electron so that it has an electron configuration like noble gas Ne

Na: 2 8 1

Ne: 2 8

so that it becomes a Na + ion

While the Cl atom will bind one electron, so it has an electron configuration like noble gas Ar

Cl: 2 8 7

Ar: 2 8 8

So that it becomes a Cl- ion

Finally, there will be an attractive attraction between positive ions and negative ions and NaCl is formed

So the bond between Na + and Cl- ions is an ionic bond
