Answer:
2.88 × 10⁻¹⁸ C
Explanation:
The charge on a proton and electron are the same and it is = 1.6 × 10⁻¹⁹ C
The net charge electric charge of an iron atom = (number of proton × charge on a proton) + ( number of electron × charge on an electron ) = 26 (e) + 8 (-e) = 26 e - 8 e = 18 e = 18 × 1.6 × 10⁻¹⁹ C = 2.88 × 10⁻¹⁸ C
Answer:
2.88x10⁻¹⁸ C
Explanation:
The net charge is given by:
[tex] Q_{net} = n_{p}*p + n_{e}*e [/tex]
Where:
np: is the quantity of protons = 26
ne: is the quantity of electrons = 8
p: is the charge of protons = 1.6x10⁻¹⁹ C
e: is the charge of electrons = -1.6x10⁻¹⁹ C
Hence the net charge is:
[tex] Q_{net} = n_{p}*p + n_{e}*e = 26*1.6 \cdot 10^{-19} C + 8*(-1.6 \cdot 10^{-19} C) = 2.88 \cdot 10^{-18} C [/tex]
Therefore, the net charge is 2.88x10⁻¹⁸ C.
I hope it helps you!
