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.
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.
A pure sample of an element contains many atoms of the same type. For example, the millions of iron atoms that make up a piece of iron metal are of the same type and have the characteristics of iron. Iron atoms, however, are very different from atoms of other elements, such as gold or oxygen.
Part 1 - Label the parts of the atom below (protons, neutrons, electrons, nucleus, quarks). - + + +. - Part 2 – Answer the following questions. 1. _______________What part of the atom has no charge? 2. _______________What part of the atom has a positive charge? 3. _______________What part of the atom has a negative charge? 4.
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.
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 ...
Electron Configuration Practice Worksheet. Note: The electron configurations in this worksheet assume that lanthanum (La) is the first element in the 4f block and that actinium (Ac) is the first element in the 5f block.
