, you will find an integer, called the atomic number, written above the symbol for each element. The atomic number, which is unique to each element, indicates the number of protons in an atom of that element. ANSWER: Hint 4. Determine the location of the particles in an atom Where are each of the particles located in an atom? Drag each item to the appropriate bin. % 3
ANSWER: Correct The diagram of an atom given here is not drawn to scale. The nucleus of the atom is very small compared to the overall size of the atom. If an atom were the size of a football stadium, the nucleus would be about the size of a marble.

Which of the following statements is true about the properties of protons, neutrons, and electrons? Hint 1. Properties of subatomic particles See Figure 4.7 and Table 4.1 on page 100.
Correct Element Names, Symbols, and Atomic Numbers Learning Goal: To identify elements by their chemical symbol and their atomic number. Chemical elements are substances that are composed of only one kind of atom and cannot be broken down into simpler substances. Elements are organized into a table called the periodic table of elements , or simply the periodic table. Each element is characterized by the number of protons in the nucleus. The number of protons in the nucleus is called the atomic number and is listed on the periodic table. No two elements have the same atomic number; therefore, elements can be identified by their atomic numbers. Elements are also identified by a unique chemical symbol that contains one or two letters to identify them. For example, the chemical symbol for oxygen is , and the chemical symbol for copper is . Part A What are the names of the elements symbolized by , , and , respectively? Spelling counts! Enter the names of the elements, separated by commas. Hint 1. How to approach the problem Many chemical symbols are based on the English name of the element. For example, the chemical symbol for oxygen is . Some elements, however, have symbols based on their Latin or Greek names. For example, the symbol for mercury is , from the Latin hydrargyrum . You should memorize the chemical symbols for common elements. ANSWER: Correct
