What is the greatest number of electrons in the first seven energy level ​

Answers

Answer 1
Answer:

Answer:

280 electrons

Explanation:

The number of electrons in each energy level are determine by using following formula:

2n²

Here "n' is the energy level. we will put the energy level number in place of "n" and number of electrons will easily found.

Principle energy levels                        number of electrons

             1                                                     2n² = 2(1)²= 2

             2                                                     2n² = 2(2)²= 8                                    

             3                                                     2n² = 2(3)²= 18

             4                                                     2n² = 2(4)²= 32

             5                                                     2n² = 2(5)²= 50

             6                                                     2n² = 2(6)²= 72

             7                                                      2n² = 2(7)²= 98

So the total number of electrons in first seven energy levels will be the sum of the number of electrons in each energy levels.

2+8+18+32+50+72+98 = 280 electrons

How does a seal belt help prevent injuries by applying a for

Answers

A seat* belt can help prevent major injuries from car crashes because it can buckle people down safely. If a car crashed into the car and you were in the front seat without a seat belt, you could catapult straight out the window. With a seatbelt on, you will be restrained and fastened to the chair and have some not major injuries. 
A seat belt helps to prevent injury in the event of a car crash by reducing the velocity of a body as it experiences a sudden decrease in speed. Due to the body's inertia, which is its 'resistance to a change in speed or direction of travel', a passenger in a vehicle will want to continue travelling forwards once the car has reached a sudden stop. If the vehicle is travelling at 50mph and crashes into a brick wall, instantly reducing its velocity to zero, the passenger will continue moving forwards at 50mph unless there is something in front of them to create a 'stopping force'. This is because the velocities of the car and passenger are independent.. Hope this helps you!(: Good luck. 

how is it possible for two parents who both express the dominate phenotype to have offspring with the recessive phenotype?

Answers

A phenotype is what you look like. The parents are showing the dominant phenotype. If we were talking about eye color, the dominant trait is brown eyes. However, the parents might have a recessive gene which is covered by the dominant one. Say they both have Bb genotypes. The capital B is brown and the lower case is blue. Their blue gene is still there, just covered by a brown one. In a punnett square, there is a 25 percent chance a child will have blue eyes (bb) In most cases, the children will end up will brown eyes. Hope that helps!

Which cell structure most resembles the human nervous system?endomembrane system

Golgi apparatus

nucleus

rough ER

Answers

The endomembrane system is the cell structure that most resembles the human nervous system. The reason for that is because it consists of a group of cell membranes and organelles that are interconnected in order to accomplish their function, similarly to those in the nervous system.
endomembrane system is the outside so this is it
