If the number of electrons and protons are not the same what do you call this?
An ION NB When an atom has a balanced(equal) number of protons and electrons it is named an ATOM If an atom has an imbalance(unequal) number of protons and electrons it is named an ION (NOT an atom). e.g. Sodium (Na)_ An atom of sodium has 11 protons (+) and 11 electrons(-). When this atom is ionized it loses ONE electron. So the count is now 11 protons(+) and 10 electrons(-). It is now an ION (NOT an atom) and is symbolically represented by ' Na^(+)'. The positive(+) because 11 protons (11+) and electrons(-) because 10 electrons (10-) Adding we have 11+ 10- = 1+ Hence the plus (+) as the ionic charge, represented by ' Na^(+) '. Conversely Chlorine(Cl) An atom of chlorine has 17 protons (+) and 17 electrons(-). When this atom undergoes electron affinity it gains ONE electron. So the count is now 17 protons(+) and 18 electrons(-). It is now an ION (NOT an atom) and is symbolically represented by ' Cl^(-)'. The positive(+) because 17 protons (17+) and electrons(-) because 18 electrons (18-) Adding we have 17+ 18- = 1- Hence the negative (-) as the ionic charge, represented by ' Cl^(-) '.
What is a mixture of sub atomic particles nuclei and electrons?
An ATOM. The sub-atomic particles are Protons, Neutrons. and Electrons. The protons and neutrons are collectively named 'nucleons, because they form the nucleus of an atom. The electrons are in energy shells around the nucleus.
What is the number of protons in the necleus?
# of protons = # of electrons # of protons/ electrons + # of neutrons = atomic mass
