The atom is the basic unit in chemistry. An atom contains neutrons, protons, and electrons. Neutrons are neutral, protons have a
positive charge, and electrons have a negative charge. Most of the time, atoms are neutrally charged, meaning that they have the same number of protons and electrons. Sometimes, though, atoms lose or gain one or more electrons, and become positively or negatively charged. A positively or negatively charged atom is called an ion. An ion with more protons than electrons is positively charged. An ion with more electrons than protons is negatively charged. One common ion is a Sodium ion, which has a charge of +1. Which of the following statements is true?
A. The ion has more electrons than protons.
B. The ion has the same number of protons and electrons.
C. The ion has more protons than electrons.
Since the ratio of roses to sunflowers is , we can represent how many there are of each as and , respectively. We know that there are more sunflowers than roses, so we can set up the following equation to solve for :
Solving for , we get:
(Subtract from both sides of the equation to isolate )
(Simplify)
(Symmetric Property of Equality)
(Divide both sides of the equation by to get rid of 's coefficient)
(Simplify)
Therefore, since , we know that there are roses and sunflowers. Hope this helps!
