Silicon has 2 isotopes, Silicon-28 with an abundance of 90% and Silicon-30 with an abundance of 10%. Find the AAM for Silicon.

JulsSmile [24]

Answer:

RAM

$RAM = (mass \: of \: ^{28} Si \: \times \%abundance) + (mass \: of \: ^{30} Si \: \times \%abundance) \\ RAM = (28 \times 90\%) + (30 \times 10\%) \\ RAM = 25.2 + 3 \\ RAM = 28.2$

How many neutrinos does an element have if it's atomic number is 47 and it's mass number is 169

Stells [14]

This element would have 122 neutrons.

Atomic mass is the accumulation of neutrons and protons.

169 - 47 = 122.

Therefore, there are 122 neutrons.
