What is the atomic number of an element with 9 protons and 10 electrons? Si a. Is this an atom, molecule, or compound? b. What is the name of it? c. How many of each sub-atomic particles does it have? Protons ___, Neut...
How many core electrons does each have? Lithium and SodiumCore Electrons:There are two types of electrons in the orbitals of an atom. One is the valance shell electron and another is the core electrons. Valance shell electrons are the electrons of the outermost shell while the core ...
Ions are formed when an atom either loses or gains electrons. The number in thesuperscriptwill tell you the magnitude of this change. Say you have Cl-. How many electron, protons and neutrons does this ion have? The process for finding these values is very similar to what was done above....
How many protons and neutrons does oxygen-18 have? What is its mass number? The 57Fe atom has how many neutrons? How many neutrons are in the nucleus of an atom of Silver-107? How many neutrons are in the nucleus of an atom of u-235? How many protons and neutrons are in magnesium...
It's not that simple though. An atom's properties can change considerably based on how many of each particle it has. If you change the number of protons, you wind up with a different element altogether. If you alter the number of neutrons in an atom, you wind up with anisotope. ...

the same element, that consists of the same number of protons but a slightly different number of neutrons. For instance, potassium can exist as one of three isotopes, each one having one more neutron, and there being slightly heavier than the last. Similarly, there are two isotopes of ...
How is the atomic mass of an element calculated? How to find the amu of an isotope? How to find the number of neutrons in an isotope Does each isotope have its own mass number, or does each element have a general mass number? If each element has a general mass number, how is that...
In my Bio Lab class we have to convert each value into the designated units. How do you convert 46,756,790 mg into kg? How many neutrons does element x have if it's atomic number is 42 and it's mass number is 154? Body mass index is a measure of obesity and it is calculated ...
How many atoms of cobalt equal a mass of 58.93 g? How many valence electrons does a neutral atom of aluminum have? How many protons, neutrons, and electrons are in aluminum? How many neutrons does aluminum have? How many atoms are in 2 Fe?
