Question

Ядро атома якого елемента має заряд 8•10-18Кл

Answer 1

N = q / e = 8·10⁻¹⁸ / 1,6·10⁻¹⁹ = 50

Это ядро олова:
Sn ₅₀¹¹⁹

Answer 2

Atomic Nucleus and Charge

The nucleus of an atom of any element contains positively charged protons and neutral neutrons. The total positive charge of the nucleus is equal to the number of protons multiplied by the elementary charge, which is approximately 1.602 x 10^-19 coulombs.

Calculation: The given charge is 8 x 10^-18 C. To find the number of protons in the nucleus, we can use the formula: \[ Q = n \times e \] Where: - \( Q \) = total charge of the nucleus - \( n \) = number of protons - \( e \) = elementary charge

So, the number of protons in the nucleus can be calculated as: \[ n = \frac{Q}{e} = \frac{8 \times 10^{-18}}{1.602 \times 10^{-19}} \approx 50 \]

Therefore, the nucleus of the atom in question has approximately 50 protons.
