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.
There are few truly single-payer systems in the developed world. Canada has one, as does Taiwan. Most countries rely on many, many insurers. Germany, for instance, has more than 150 âsickness funds.â The Swiss and Dutch health systems look a lot like Obamacareâs health-insurance exchanges. In France, about 90 percent of citizens have supplementary health insurance. Sweden has moved from a single-payer system to one with private insurers.
