What is the symbol for the isotope with 80 protons and a mass number of 202? How many neutrons does it have?Mass Number:The mass number of an atom represents the number of nucleons in the nucleus of an atom. Nucleons is a general term for p...
How many neutrons does element x have if it's atomic number is 42 and it's mass number is 154? Which of the following is chemically inert (unreactive)? A) sodium (atomic number 11) B) oxygen (atomic number 8) C) carbon (atomic number 6) D) neon (atom...
There are many different ways to produce photons, but all of them use the same mechanism inside an atom to do it. This mechanism involves the energizing of electrons orbiting each atom's nucleus. How Nuclear Radiation Works describes protons, neutrons and electrons in some detail. For example,...

How many protons, neutrons, and electrons does the chlorite polyatomic ion have? How many valence electrons does the below atom have? arsenic, Z = 33 How many total valence electrons are in AlCl3? How many ions of each type (cation, anion) are in L i 2 O ? How many core electrons ...
Everything we do is controlled and enabled by electrical signals running through our bodies. As we learned in intro physics, everything is made up of atoms, and atoms are made up of protons, neutrons and electrons. Protons have a positive charge, neutrons have a neutral charge, and electro...
How many protons are in an isotope of sodium with a mass number of 25? How is an atom's atomic mass number determined? How do you calculate atomic number? A certain isotope X^+ contains 54 electrons and 78 neutrons. What is the mass number of this isotope? How many neutrons are in ...
example,carbon atomsalways have six protons;hydrogen atomsalways have one; andoxygen atomsalways have eight. Different versions of the same element, called isotopes, can have a different number of neutrons. Elements can also gain or lose electrons to become charged, in which case they are called...
(hadrons). As the temperature falls, these hadrons combine to form the nuclei of atoms, such as deuterium (one proton and one neutron) and helium (two protons and two neutrons). The nucleus of deuterium is known as the deuteron, and the nucleus of helium is the α-particle, familiar ...
How many protons are in an isotope of sodium with a mass number of 25? What is the mass number of the hydrogen isotope that contains 2 neutrons? How can you find atomic number from mass number? How do you calculate atomic mass from atomic number?
