Silicon must have 4 single covalent bond, every single bond has 2 electrons (one pair), so 4·2=8 electrons (octet).

NEED ASAP THANK YOU!
Bezzdna [24]

Answer:

d. 10

Explanation:

The 24 means the atomic mass and twelve means the number of electrons. You subtract the number of electrons from the atomic mass. 24-12=12

Then, since there's +2, you subtract 2 from 12 which equals 10 which means there are 10 electrons now.

The confusing thing is that + means subtract and - means add here.

Hope this helps.

Similarities and differences between covalent bonds and molecular interactions
yan [13]
Covalent bonds are formed between atoms which have 
<span>- unsatisfied valency </span>
<span>- no inert gas electronic configuration </span>
<span>- These are directional bonds </span>
<span>- formed by sharing of electrons </span>

<span>Intermolecular forces </span>
<span>- much weaker than covalent bond </span>
<span>- These are not directional (except Hydrogen bonds) </span>
<span>- These are more electrostatic in nature </span>
<span>- exist between stable molecules </span>
<span>- can be Hydrogen bonding, dipole-dipole and induced dipole-induced dipole </span>

8255 min = _?_days<br> I need help please
Ksivusya [100]

Answer:

5.733 days

Explanation:

To convert from minuets to days we must first convert minuets to hours. To do this we divide by 60 since there are 60 minuets in one hour.

8255 min ÷ 60 = 137.6 hr

Now that we have the amount of hours we can convert to days by dividing by 24 since there are 24 hours in one day.

137.6 hr ÷ 24 = 5.733 days
