Covalent bonds form when electrons are shared between atoms and are attracted by the nuclei of both atoms. In pure covalent bonds, the electrons are shared equally. In polar covalent bonds, the electrons are shared unequally, as one atom exerts a stronger force of attraction on the electrons than the other.
Answer:
Explanation:
Given that,
The uncertainty in the position of an electron along the x-axis is, 
We need to find the east uncertainty in any simultaneous measurement of the momentum component of this electron.
We know that the Heisenberg's uncertainty principle gives the relation between the uncertainty in position and the momentum of electron as :
Putting all the values, we get :
So, the momentum component of this electrons is greater than 
.
Answer:
B. 14
Explanation:
For an element:
- Atomic number: is the number of protons in the nucleus (p)
- Mass number: it is the number of protons (p) + neutrons (n) in the nucleus
For Al (aluminium), we have:
p = 13
p + n = 27
Substituting the first equation into the second one, we find the number of neutrons:
n = 27 - p = 27 - 13 = 14
Electricity and magnetism can be considered as part of the same phenomenon because both are generated by electromagnetic forces.
<h3>What is electricity?</h3>
Electricity is the movement or flow of negatively charged electrons through a suitable conductor where a charge is applied.
Moreover, magnetism is a natural phenomenon caused by the generation/movement of electric charges.
In conclusion, electricity and magnetism can be considered as part of the same phenomenon because both are generated by electromagnetic forces.
