True or false: chemical reactions happen and compounds form because they're trying to get 6 electrons in their outer orbitals
wel

Answer:

False

Explanation:

The octet rule forms the basis for chemical reactions. The octet rule states that; an atom is only stable when it has eight electrons around its outermost shell.

This implies that the driving force behind chemical reaction is the attainment of an octet structure(eight electrons in the outermost shell of each of the bonding atoms).

An atom that has only six electrons in its outermost shell is not yet stable according to the demand of the octet rule. Hence, the statement "chemical reactions happen and compounds form because they're trying to get 6 electrons in their outer orbitals" is false.

If we accelerate a radioactive isotope of an element in a particle accelerator to a speed close to that of light, what would its
Radda [10]

When the speed of the particle is close to that of light, it's observed mass would be infinitely large.

To answer the question, we need to know what observed mass is.

<h3>What is observed mass in relativity?</h3>

This is the mass the body of an object in relativistic motion appears to have.

So, observed mass, m' = m/√(1 - β²) where

  • m = rest mass and
  • β = relative velocity of isotope to light.

Now, since the speed of the particle is close to that of light, β ≅ 1.

So, m' = m/√(1 - β²)

m' = m/√(1 - 1²)

m' = m/√(1 - 1)

m' = m/√0

m' = m/0

m' = ∞

So, when the speed of the particle is close to that of light, it's observed mass would be infinitely large.
