New to group...urgent question
hi everyone, i am a college student taking a pre-anatomy class. we
are having a quiz tomorrow over the intro chemistry chapter and i
would greatly appreciate it if someone could help me with the
following:
i have a problem in my book to solve: 14 (superscript) C. I am to
find the # of protons, # of neutrons, # of electrons and the mass
number. Obviously, I understand that the mass number is 14.
HOWEVER, when my book has no periodic table, and a table
isn't even discussed in the chapter, how the heck do i figure out
the # of protons, electrons and neutrons just by looking at 14C.
Also, I am having trouble learning how to balance equations.
Can someone PLEASE help me with that as well? Thank you so
much.... :)[b][size=18][/size][/b]
Carbon 14 is another isotope of carbon. The isotope number indicates the mass number. The mass number relates to the theoretical mass of the nucleus of a particular element. The nucleus consists of protons and neutrons.
The atomic number is the number of protons for a particular element. Carbon has a atomic number of 6 (an element, regardless of which isotope always has the same mass number; the mass number is the "main number" of each element on the periodic table). Thus C 14 has 6 protons, 8 neutrons (14-6), and 6 electrons (number of protons=number of electrons for any element which is non-ionized).
Just ask me if you are having any specific problems on balancing equations.
