How To write an electron configuration: Determine the total number of electrons to be represented. Use the Aufbau process to fill the orbitals with electrons. The Aufbau process requires that electrons fill the lowest energy orbitals first. In another words, atoms are built from the ground upwards.
Atomic Basics Answer Key Part A: Atomic Structure 1. Draw five protons in the nucleus of the atom. Label them with their charge. 2. Draw six neutrons in the nucleus of the atom. 3. Draw two electrons in the first energy level and label them with their charge. 4. Draw three electrons in the second energy level and label them with their charge. 5.
An atom of an element has two electrons in the first energy level and five electrons in the second level. Write the electron configuration for this atom and name the element.
Use the figure below to answer the following questions. b. a. How many valence electrons does an atom of this element have? b. What is the atom’s electron-dot structure? c. If enough energy was added to remove an electron, from which energy level would the electron be removed? Explain your answer. 13. What is the ground-state electron ...
Vocabulary Review Key atom: the smallest particle of an element that has all the properties of that element. The atom has nocharge. The 3 main subatomic particles that make up the atom are the proton, neutron and electron. nucleus: small, dense positively charged center of an atom. protons and neutrons are found in the nucleus.
Information: Structure of the Atom. Note the following symbols: (they are not to scale) = proton (positive charge) = electron (negative charge) = neutron (no charge) The following three diagrams are hydrogen atoms: 1 H. 1. The following three diagrams are carbon atoms: 2. 1 H.
How does light reveal the behavior of electrons in an atom? Why? From fi reworks to stars, the color of light is useful in fi nding out what’s in matter. The emission of light by hydrogen and other atoms has played a key role in understanding the electronic structure of atoms.
