How many protons and neutrons are in mendelevium? How many neutrons does carbon-12 have? How many neutrons are in the radioactive isotope 40/19k? How many neutrons are in iodine-131? What is the mass number of argon? How many neutrons does potassium have?
A neutral atom is one that has an equal number of protons and electrons. The positive charge of the protons and the negative charge of the electrons will cancel each other out. In the case of argon, it has 18 protons and thus will be neutral if it has 18 electrons in total betwe...
How many electrons are present in the 2nd energy level of potassium? How do you show the number of protons and neutrons on a Bohr-Rutherford diagram? How many cm^3 does a 55.932 g sample of copper occupy if it has a density of 8.92 g/cm^3? How do the electrons help in predicting ...
All elements are arranged in the periodic table by their atomic number -- the number of protons in their nucleus. Aluminum's lucky number is 13, so an aluminum atom has 13 protons. It also has 13 electrons. The elements located above and below aluminum on the periodic table form a ...
When ethanol is oxidized to acetic acid, two protons and two electrons are also produced. Read More Breathalyzers FAQs How long after drinking can you pass a breathalyzer test? This depends entirely on your metabolism. Some digest and pass alcohol faster while some are slow. In general, ...
In fact, several inches of lead or even a few feet of concrete are required to stop gamma rays. They are a radiation hazard for the entire body, meaning that although they will pass through you, your tissue will absorb some rays. Gamma rays occur naturally in minerals like potassium-40....

OK, so when a cell is in the RMP stage, sodium and potassium ions are both present on either side of the membrane. Cool beans. But — how do they cross the barrier? How does an ion enter or exit a cell? Well, that’s whereion channelscome in. As the name implies, these are ch...
How to determine which quantum numbers are possible? I don't know why I got this question wrong. What is the maximum number of electrons that can occupy the 2s orbital. I answered 8. Why is this incorrect? Thanks How many electrons are present in the 2...
Protons and neutrons bind together to form the nucleus of the atom, while the electrons surround and orbit the nucleus. Protons and electrons have opposite charges and therefore attract one another (electrons are negative and protons are positive, and opposite charges attract). In most cases, ...
