Atomic number of hydrogen is 1 and one dot in that lewis structure displays only one electron. So, in bespeak to complete its octet it requirements one much more electron.

You are watching: Which lewis dot diagram shows an atom that needs 2 more electrons in its outermost shell

Atomic number of carbon is 6 and its electronic distribution is 2, 4. Carbon demands 4 more electrons in order to finish its octet.

Atomic number of oxygen is 8 and its electronic circulation is 2, 6. In bespeak to finish octet, oxygen demands 2 an ext electrons.

Atomic variety of fluorine is 9 and also its electronic circulation is 2, 7. In stimulate to complete octet, fluorine needs 1 more electron.

Hence, we can conclude that out of the offered options, lewis dot structure of oxygen atom demands 2 much more electrons in that outermost shell.

As much more resistors are included in parallel across a continuous voltage source, the power provided by the source
kaheart <24>

As an ext resistors are added in parallel throughout a constant voltage source, over there are more paths for present to take. So more current dribbles out of the source, and the complete current supplied by the resource increases.

The power supplied by the battery is (voltage) x (current). Therefore if the voltage is consistent and the current increases, the power being supplied must additionally increase.

Distribution strongness is commonly divided into three levels:
gregori <183>
It is indeed divided into Intensive, exclusive, and selective disribution. Let me explain them. As soon as we talk around Intesive circulation we say the we have actually a strategy that is designed come place commodities in as countless outlets as possible. The exclusive circulation is once we recognize policy by granting exclusive geographic territories to one or very few retail customers so no various other retailers in the territory have the right to sell a particular brand. And also when we talk about selective circulation we recognize that it lies in in between the intensive and exclusive circulation strategies due to the fact that it offers a couple of selected customers in a territory

Refer to the diagram shown below.The basket is represented by a weightless strict beam of size 0.78 m.The x-coordinate is measured indigenous the left end of the basket.The mass in ~ x=0 is 2*0.55 = 1.1 kg.The weight exhilaration at x = 0 is W₁ = 1.1*9.8 = 10.78 NThe mass near the right finish is 1.8 kg.Its weight is W₂ = 1.8*9.8 = 17.64 NThe fulcrum is in the center of the basket, thus its place isx = 0.78/2 = 0.39 m.For equilibrium, the amount of moments around the fulcrum is zero.Therefore(10.78 N)*(0.39 m) - (17.64 N)*(x-0.39 m) = 04.2042 - 17.64x + 6.8796 = 0-17.64x = -11.0838x = 0.6283 0.63 m native the left end.

Shaun is 68 miles away from Keegan. They space traveling in the direction of each other. If Keegan travel 7 mph much faster than Shaun and they me
PilotLPTM <1.2K> , vk=7+vs=12mph

Explanation: kinematics with continuous speed

(shaun) xs = 0 + vs*t

(keegan) xk= 68 - vk*t

they meet after t= 4hours (xs=xk):

vs*t= 68-vk*t

but we know that vk=7+vs ( keegan faster) replacing:

vs*4= 68-(7+vs)*4

solving vs=5mph , vk=7+vs=12mph
