How many electrons neutrons and protons are in 3H?

Question

I need to know how many electons neutrons and protons are in 3H
14N, 12C, 14C, 10B, 11B, 16O, 16O-2, 7Li, 7Li+1, 5He, 16O, 22F, 2H, 22Ne, 23Na. Please help out i have no clue how to do this stuff. Thanks alot

Answer 1

Atomic number of H ie hydrogen = 1 (From periodic table. See http://en.wikipedia.org/wiki/List_of_elements_by_number) as Atomic Number = number of protons and in an electrically neutral atom (ie no charge) number of protons has to equal num,ber of electrons

So it has 1 proton (charge: +1) and 1 electron (charge: -1).

Now the mass of an electron is insignificant compared to the mass of a proton and a neutron whose masses are almost equivalent The 3 says the nuclear mass is 3 and the way this is made up is by 1 proton ( to balance the charge of the 1 electron) and 2 neutrons. (Atomic mass 3 - atomic number 1 = 2 or if you prefer no of protons (= atomic number) + number of neutrons = atomic mass)

So 3H: 1e-, 1p+, 2n

14N: Nitrogen - Atomic number 7 so 7e-, 7p+, and (14 - 7 =) 7n (ie number of neutrons = mass 14 - atomic number 7 = 7)

12C: Carbon - atomic number 6 so 6e-, 6p+, (12 - 6 =) 6n

14C: Carbon - atomic number 6 so 6e-, 6p+, (14 - 6 =) 8n (this is an isotope of carbon)
........................

16O-2 This is an ion of oxygen as it has 2 additional negative charges ie 2 EXTRA electrons
So: O-2 ion - atomic number 8 so (8 + 2 = )10e-, 8p+, (16 - 8 =) 8n

I think you can do the rest (just remember if the ION is charged positively it is electron deficient (NOT proton abundant) as it is electrons that are gained or lost by atoms to form ions ... gaining protons changes the atomic number and hence the element)

Answer 2

3H 1proton , 2 neutrons, 1 electron
14N 7 protons; 7 neutrons, 7 electrons
12C 6 protons; 6 neutrons, 6 electrons
14C 6protons; 8 neutrons, 6 electrons
10B 5protons; 5 neutrons, 5electrons
11B 5protons; 6neutrons, 5 electrons
16O 8protons; 8neutrons, 8electrons
16O2- 8protons; 8 neutrons, 10 electrons
7 Li 3 protons; 4 neutrons, 3 electrons
7 Li 3 protons; 4 neutrons, 2 electrons
5He 2protons; 13 neutrons, 9 electrons
2H 1proton; 1 neutron, 1 electron
22Ne 10protons 12 neutrons, 10 electrons
23 Na 11protons , 12 neutrons, 11 electrons

easy for protona and electrons you use the periodic table Z is number of protons and electrons when atom in native state.
For neutrons, you use the mass number and substract number of protons. For ionized species add one electron for one negative charge , substract 1 electron for positive charge

Answer 3

For any atom, the number of protons is just the atomic number of the element. If the atom is uncharged, the number of electrons is equal to the number of protons. If the charge is +1, there is one electon less than the number of protons. The number of neutrons is the mass number minus the number of protons.

Good luck.

Answer 4

2 neutrons and one proton. the quantity of electrons isn't desperate via the call "H-3" ("Hydrogen-3"), yet because of the fact there is one proton, it may tend to have one electron. H+ is extra probable than H- (no electrons is extra probable than 2 electrons).
