Answer:

Which of the following elements is going to be the most reactive and why? Nitrogen or Oxygen?
bagirrra123 [75]

Answer:

(C) Oxygen because it has the strongest attractive force and the largest

electronegativity

Explanation:

Oxygen will be most reactive

configuration = 1s^22s^22p^4

As oxygen need only two electrons to complete its octet.

Oxygen will have stronger force than nitrogen as it will tend to pull electrons more to complete its octet. Also along the period electronegativity increases so oxygen has higher electronegativity than nitrogen

An element has three naturally occurring isotopes. ten percent (.10) occurs as 55^x, fifteen percent (.15) occurs as isotope 56^
Leviafan [203]
The average atomic weight is, from the name itself, the average weight of all its naturally occurring isotopes. All you have to do is multiple the abundance of each isotope with its individual mass, then add them altogether.

Mass = (0.10*55)+(0.15*56)+(.75*57)
<em>Mass = 56.65 amu</em>
