Answer:
0
Step-by-step explanation:
We are given that each electron in an atom has a charge of -1 and each proton has a charge of +1.
The charge of 2 electrons will be:
2 * (-1) = -2
The charge of 2 protons will be:
2 * 1 = 2
The overall charge is the sum of the charge of the 2 electrons and the 2 protons. That is:
-2 + 2 = 0
The overall charge is 0.
Answer:
positive
Step-by-step explanation:
the discriminant of the function is postive.
because from the graph we notice that it has 2 intercepts on x-axis, which means the function has 2 real solution when y=0
that implies the discriminant is positive.
if we have 2 distinct real solution
if we have no real solution but 2 complex solutions
if we have 2 identical real solution
