Which one has a positive charge, a negative charge, and no charge? Protonâpositive; electronânegative; neutronâno charge. The charge on the proton and electron are exactly the same size but opposite. The same number of protons and electrons exactly cancel one another in a neutral atom. Note: The picture shows a simple model of the carbon atom.
What is Single Payer? Single-payer national health insurance, also known as âMedicare for all,â is a system in which a single public or quasi-public agency organizes health care financing, but the delivery of care remains largely in private hands.
Though a public option and single payer system are often discussed in tandem, they are very different. A public option is a single plan that would exist alongside private plans, while single payer refers to an entire public healthcare system. Think of the public option as Medicare for More, whereas single payer is often called Medicare for All. Helen Halpin, a professor at the U.C. Berkley School of Public Health, says the introduction of a public option could help transition the U.S. to a single-payer program down the road.
