What is the expected mass (in kg) of a 10 over 5 b isotope? 1 proton = 1.6726 × 10-27 kg 1 neutron = 1.6749 × 10-27 kg a.1.67 × 10-26 kg b.1.67 × 1026 kg c.2.51 × 10-26 kg d.2.51 × 1026 kg

An atom of this isotope contains 5 protons and 10-5=5 neutrons.



The answer is A. 1.67 × 10⁻²⁶ kg.

All the elements are arranged by melting points on the periodic table. in row they go from metals to gasses. in the row from sodium to argon, sodium is more reactive than the one on its right, magnesium.
