Answer:
<h3><em><u>Magnesium has an atomic number of 12, which means its neutral atom has 12 electrons. The Mg2+ ion is formed when the neutral magnesium atom loses 2 electrons, which brings its total number of electrons to 10</u></em></h3>
Answer:
p = 60.6N*s
Explanation:
v_f = v_0+a*t
a = (v_f-v_0)/t
a = (1.8m/s)/2.35s
a = 0.77m/s²
F = m*a
F = (25kg+8.5kg)*0.77m/s²
F = 25.8N
^p = F*t
p = 25.8N*2.35s
p = 60.6N*s
Answer:
-3.2 ×1.6 ×10^-19C
Explanation:
Number of proton = 6
Number of electron = 8
To determine the quantity of the charge, we would first find the difference between the number of
protons and electrons. Then multiply the difference by charge 1.6 x 10 -19 C to determine the charge on the object.
Difference between proton and electron is elementary charge
Elementary charge = proton - electron
= 6 - 8
Elementary charge = -2e
Recall, charge (q) = 1.6 ×10^-19C
1e = 1.6 ×10^-19C
Magnitude of the charge of object = -2× (1.6 ×10^-19C)
Magnitude of the charge of object = -3.2 ×1.6 ×10^-19C
