Answer:
The total charge on atom is -2.
Step-by-step explanation:
We are given the following in the question:
Electrons have a negative charge.
Let this charge be represented by -1.
Protons have a positive charge. Let this charge be represented by +1.
An atom have 2 more electrons than protons.
Let 
be the number of protons.
Then, the number of electrons are 
Total charge on atom =
=Charge on atom = Charge of protons + Charge of electrons
Thus, the total charge on atom is -2.
Answer:
median is 75 and range is 45
Step-by-step explanation:
range is largest number - smallest number so 95-50=45
Median is the medium of all the data. The medium is shown by the middle line in the box portion of the plot.

Vertex=(-1,0)
x^2-2x-1
y=− ( x + 1 )^2 + 0
Use the vertex form, y=a(x−h)^2+k, to determine the values of a, h, and k.
Find the vertex (h,k) = (-1,0)
Answer:
1) -10^3 (-10 to the power of 3)
2) r^5 (pie to the power of 5)
3) 1/2^2 + x^3 (1/2 to the power of 2 + x to the power of 3)
