- All ions have at least one ________ select all that are correct. a. proton c. electron b. neutron d. all of the abovePolonium is a rare element with 33 radioisotopes. The most common one, P210o, has 84 protons and 126 neutrons. When P210o decays, it emits an alpha particle, which is a helium nucleus 2 protons and 2 neutrons. P210o decay is tricky to detect because alpha particles do not carry very much energy compared to other forms of radiation. For example, they can be stopped by a single sheet of paper or a few inches of air. That is one reason why authorities failed to discover toxic amounts of P210o in the body of former KGB agent Alexander Litvinenko until after he died suddenly and mysteriously in 2006. What element does an atom of P210o change into after it emits an alpha particle.An isotope of sodium (Na) has a mass number of 22. How many neutrons does it have? a. 11 b. 12 c. 22 d. 44

- Visit this website (http://openstaxcollege.org/l/ptable) to view the periodic table. In the periodic table of the elements, elements in a single column have the same number of electrons that can participate in a chemical reaction. These electrons are known as valence electrons. For example, the elements in the first column all have a single valence electron—an electron that can be donated in a chemical reaction with another atom. What is the meaning of a mass number shown in parentheses?The number of protons in a neutral (no charge) atom equals the number of ions. isotopes. neutrons minus electrons. electrons. elements.The mass number of an atom depends primarily on the number of protons and neutrons. positrons. neutrons and electrons. protons and electrons.
- Atoms of the same element that differ only in the number of neutrons are known asWhy the Number of Electrons Matter Since we know each element as a defined number of protons, we can also use that number to determine the number of electrons, assuming the element has no charge. Let’s write some out: ELEMENT NUMBER OF PROTONS NUMBER OF ELECTRONS C A B O C D Al E F Na G H Si I Jtwo atms of an element have the same number of protons electrons plus neutrons protons plus neutrons electrons
