Question

diagrams that are used to represent valence electrons: dot to dot structures bohr models lewis dot structures octet structure which element does this bohr model represent? calcium silicon germanium sulfur

Explanation:

1. Lewis dot structures are used to represent valence - electrons. They show the symbol of the element and the number of valence electrons as dots around it.
2. To determine the element from the Bohr model, count the total number of electrons. The first shell can hold 2 electrons, the second shell 8, and the third shell 8. Counting the electrons in the given Bohr model, we have 2 + 8+ 4 = 14 electrons. The atomic number of an element is equal to the number of electrons in a neutral atom. Silicon has an atomic number of 14.

Answer:

1. C. Lewis dot structures
2. B. Silicon
