The Composition of Atoms Quick Check
Science 8 Q1 / Matter Interactions
A model of an atom shows eight electrons in rings that represent different energy levels. How many electrons are in each energy level?(1 point)
Responses
four in the first energy level, four in the second energy level
eight in the first energy level, zero in the second energy level
zero in the first energy level, eight in the second energy level
two in the first energy level, six in the second energy level
what is the correct answer
The correct answer is: two in the first energy level, six in the second energy level.
The correct answer is: four in the first energy level, four in the second energy level.
The correct answer is: two in the first energy level, six in the second energy level.
To determine the number of electrons in each energy level, we need to refer to the electronic configuration or orbital filling order. According to the Aufbau principle, electrons fill the lowest energy levels first before moving to higher energy levels.
In this case, the model of the atom shows eight electrons, so we need to distribute them among the energy levels. The first energy level can hold a maximum of 2 electrons, while the second energy level can hold a maximum of 8 electrons.
Therefore, we place two electrons in the first energy level and six electrons in the second energy level, resulting in two in the first energy level and six in the second energy level.
