QuestionHow many electrons are in a ${ }^{209} \mathrm{Bi}$ atom?

Studdy Solution

STEP 1

Assumptions1. The atom is neutral, meaning it has the same number of protons and electrons. . The atomic number of Bismuth (Bi) is83, which means it has83 protons.

STEP 2

Since a neutral atom has the same number of protons and electrons, the number of electrons in a neutral atom of Bismuth (Bi) is equal to its atomic number.
$Number\, of\, electrons = Atomic\, number$

STEP 3

Plug in the atomic number of Bismuth (Bi) to find the number of electrons.
$Number\, of\, electrons =83$ So, an atom of ${ }^{209} \mathrm{Bi}$ has83 electrons.
