Question

1. base your answer(s) to the following question(s) on the information below and on your knowledge of chemistry.

the bohr model of the atom was developed in the early part of the twentieth century. a diagram of the bohr model for one atom, in the ground state, of a specific element is shown below. the nucleus of this atom contains 4 protons and 5 neutrons.
state the number of electrons in each shell in this atom in the ground state.
4 - 2 = 2
shell 1 = 2
shell 2 = 2

Explanation:

Step1: Determine the number of electrons

In a neutral atom, the number of electrons equals the number of protons. Given there are 4 protons, so there are 4 electrons.

Step2: Distribute electrons to shells

The first shell (closest to the nucleus) can hold a maximum of 2 electrons. After filling the first shell with 2 electrons, the remaining electrons \(4 - 2=2\) go to the second shell.

Answer:

First shell: 2 electrons; Second shell: 2 electrons.
