CP4+Neutral+Atoms

= ** __ Neutral Atoms: __ An atom with an equal number of protons and electrons ** = __ ** Example: In this case, Iron is neutral because it has 26 electrons, 29 neutrons, and 26 protons. ** __

** 1). Is the atom still neutral if the number of neutrons is different than the number of protons and electrons? ** You cannot answer this because neutrons do not apply to the charge of the atom. ** Maybe, depending on whether the protons and electrons are equal. **  **  Yes, in order for an atom to be neutral, the number of protons and electrons need to be equal. The amount of neutrons does not have to be equal to the amount of protons and electrons.  **

** 2). In a neutral atom, if you know the number of electrons can you figure out what the element is? ** ** Yes- it is the same as the protons which is the atomic number. **

** 3). If Iodine is neutral, how many electrons does it have? ** ** 53 electrons. **

** 4). How do you determine if an atom is neutral or not? ** ** If the electrons are equal to the portons. **

** 5). How do you figure out the number of neutrons in a neutral atom? ** If it was not a neutral atom you would find the neutrons in the same way.  ** Atomic Mass -(minus) atomic number. **
