Types of Electron Configuration Practice Problems, Electron configuration practice worksheet with answers
The worksheet includes various types of practice problems to cater to different levels of understanding and difficulty:
- Determining electron configuration:Students are given the atomic number of an element and asked to determine its electron configuration.
- Predicting electron distribution:Students are given an electron configuration and asked to predict the number of electrons in each energy level.
- Relating electron configuration to properties:Students are presented with electron configurations and asked to identify the element’s group and period in the periodic table, as well as its valence electrons.
Steps for Solving Electron Configuration Problems
To solve electron configuration problems effectively, students should follow these steps:
- Identify the atomic number:Determine the number of protons in the nucleus, which equals the atomic number.
- Use the Aufbau principle:Fill the orbitals in the order of increasing energy levels, starting with the lowest energy level (1s).
- Follow Hund’s rule:When filling orbitals with the same energy level, distribute the electrons so that they occupy separate orbitals with parallel spins.
- Verify the electron count:Ensure that the total number of electrons in the electron configuration matches the atomic number.
Answer Key
Problem Number | Problem Statement | Correct Answer | Explanation |
---|---|---|---|
1 | Determine the electron configuration of carbon. | 1s22s22p2 | Carbon has an atomic number of 6, so it has 6 electrons. Following the Aufbau principle, we fill the 1s, 2s, and 2p orbitals. |
2 | Predict the number of electrons in the 3d orbital of vanadium. | 5 | Vanadium has an atomic number of 23, so it has 23 electrons. The 3d orbital can hold a maximum of 10 electrons, and it is the fifth energy level to be filled. |
3 | Identify the element with the following electron configuration: 1s22s22p63s23p5. | Chlorine | This electron configuration has 17 electrons, corresponding to chlorine. It is in Group 17 (halogens) and Period 3 of the periodic table. |
