Lewis symbol
from class: Intro to Chemistry Definition A Lewis symbol is a notation that represents the valence electrons of an atom as dots around the element's symbol. It helps visualize the bonding capacity of an element in molecules.
congrats on reading the definition of Lewis symbol . now let's actually learn it.
Predict what's on your test 5 Must Know Facts For Your Next Test Lewis symbols focus on valence electrons, which are crucial for chemical bonding. Each dot in a Lewis symbol represents one valence electron. Lewis symbols are used to predict the number and types of bonds an atom can form. Elements in the same group have similar Lewis symbols because they have the same number of valence electrons. Lewis symbols do not show inner-shell electrons; they only depict outer-shell (valence) electrons. Review Questions What information does a Lewis symbol provide about an element? How many dots would you draw around the symbol for carbon in its Lewis symbol? Why do elements in the same group have similar Lewis symbols?
