the force between the electron and the proton.
a) Use F = k * q1 * q2 / d²
where k = 8.99e9 N·m²/C²
and q1 = -1.602e-19 C (electron)
and q2 = 1.602e-19 C (proton)
and d = distance between point charges = 0.53e-10 m
The negative result indicates "attraction".
the radial acceleration of the electron.
b) Here, just use F = ma
where F was found above, and
m = mass of electron = 9.11e-31kg, if memory serves
a = radial acceleration
the speed of the electron.
c) Now use a = v² / r
where a was found above
and r was given
<span> the period of the circular motion.</span>
d) period T = 2π / ω = 2πr / v
where v was found above
and r was given
Answer:
For gene therapy, stem cells can be trained in a lab to become cells that can help fight disease. Liposomes. These fatty particles have the ability to carry the new, therapeutic genes to the target cells and pass the genes into your cells' DNA.

The Lewis structure depicts the number valence electrons surrounding an atom. These are the electrons present in the outer shells which can participate in bonding with another atom or remain as non-bonding (lone pair) electrons.
In the given example there are 7 dots or 7 electrons surrounding a Cl atom. This corresponds to 7 valence electrons with a configuration that can be given as: s²p⁵ and specifically, 2s²2p⁵
