Answer:
The charge on the ion is +3.
Step-by-step explanation:
We are given the following in the question:
Number of protons = 26
Number of electrons = 23
Charge on 1 proton = +1
Charge on one electron = -1
We have to calculate the total charge on the ion.
Total charge on ion =
=(Number oof proton)(Charge of proton) + (Number of electron)(Charge of electron)
Thus, the charge on the ion is +3.
Answer: The equation of the circle is
Step-by-step explanation: We are given to write the equation of the circle with radius √13 units and center at the point (-9.3, 4.1).
We know that
the standard equation of a circle with radius r units and center at the point (h, k) is given by
In the given circle,
radius, r = √13 units and center, (h, k) = (-9.3, 4.1).
Therefore, the equation of the circle will be
Thus, the equation of the circle is
