A model of a atom shows eight electrons in rings that represent different energy levels how many electrons are in each energy level
1. Two in the first energy level, six in the second energy level.
2. The electron has a negative charge and is found outside of the nucleus.
3. Subtract the atomic number from the mass number.
4. The number of protons in the atom.
Yep connect 6th grader is 100% correct tysm!
To determine the number of electrons in each energy level of an atom, you need to know the atomic number of the element. The atomic number is given by the number of protons present in the nucleus of an atom.
The distribution of electrons in energy levels is governed by a set of rules known as the "Aufbau principle" and the "Pauli exclusion principle." According to these principles:
1. The first energy level (also called the K shell) can hold a maximum of 2 electrons.
2. The second energy level (also called the L shell) can hold a maximum of 8 electrons.
3. The third energy level (also called the M shell) can hold a maximum of 18 electrons.
4. The fourth energy level (also called the N shell) can hold a maximum of 32 electrons.
Following this, subsequent energy levels can hold even more electrons.
To determine the number of electrons in each energy level, you can use the following formula:
Number of Electrons in Energy Level = 2n²
Where 'n' represents the energy level number (K = 1, L = 2, M = 3, N = 4, etc.).
For example, let's consider oxygen (atomic number 8). Its electron configuration is 2-6, meaning it has 2 electrons in the first energy level (K shell) and 6 electrons in the second energy level (L shell).
