Question

How many protons, neutrons, and electrons are in a neutral atom with the symbol 41Ca A) 20 protons, 21 neutrons, 21 electrons B) 20 protons, 21 neutrons, 20 electrons C) 21 protons, 21 neutrons, 20 electrons D) 41 protons, 0 neutrons, 41 electrons

Answer 1

is there a picture or illustration??

Answer 2

Chemical symbol is Ca. Look up its atomic # on the periodic table to figure out it's proton count.

From there, it's neutral, so # of protons = # of electrons

Finally, # of neutrons = mass # - # of protons
the mass # is 41 as indicated by 41Ca
