Carbon and fluorine have the same shielding effect True or False

Chemistry
1 answer:
iragen [17]3 years ago
7 0

Answer:

true

Explanation:

There are two electrons (in the 1s orbital) on both carbon and fluorine “shielding” the outer electrons from the full force of the nucleus and due to both atoms being approximately the same size (both period two) then it is this shielding effect and proton difference that is causing the electronegativity difference

Which of the following statements explains why atoms are always neutral in charge
laila [671]

Answer:

D. They have the same number of protons as electrons.

Explanation:

Protons are found in the nucleus of the atom and have a positive charge while electrons orbit around the nucleus and have a negative charge. Usually, in a neutral atom of an element, the number of protons is equal to the number of electrons. This is why the atom has no charge because the positive and negative charges cancel out. When an atom loses an electron its charge turns positive while when it gains an electron its charge turns negative.

1)Define potential Energy.
Margarita [4]

1. Potential Energy is stored energy a object has when it's not moving.

2. Potential Energy is it's highest on the first stage because as you see the roller coaster is bout to go down the tract which is going to higher the kinetic energy and lower the potential energy.

3. Kinetic Energy is the amount of energy a object has when it's in motion or moving.

4. Kinetic Energy is it's highest in the third stage after it's gone down the tract and potential energy fully decreased and it's at zero.

Remember that potential energy is stored energy so when a object is not moving in this case the roller coaster isn't moving on the first stage when its bout to go down the roller coaster. Kinetic energy is the amount of energy a object has when it's in motion so in this case the third stage would have the highest example of Kinetic energy because it's fully in motion and has no potential energy.
