e- = electron
p+ = proton
N = neutron
The three main parts to an atom would be Protons, Electrons and Neutrons. Then you have sub-atomic particles, Sub - Neutrons, so on so forth
the neutron and the protons in the nucleus and the electrons in orbit around the nuclues
The name helium tells that its atomic number is 2, containing 2 protons in each atom. The numerical part of the name shows that each atom also has one neutron.
Lithium's atomic number is 3. Thus, it has 3 protons in each atom, all of which have a +1 charge. To be electrically neutral then, lithium must also have 3 electrons per atom.
The dot structure begins with a P atom in the center, with four singly bonded O atoms, one at each cardinal direction. Each O atom has a pair of dots on the unbonded sides. Finally, the structure is bracketed and noted with a 3- superscript.
The chemical symbol for lithium nitride is Li3N. In Li3N, each lithium atom has an oxidation number of +1, while the nitrogen atom has an oxidation number of -3.
In its nucleus
Ammonia is not an element and therefore does not have either a symbol or valency. Instead it has the chemical formula NH3.
Lithium is an element with 3 protons in each atom.
Protons, Electrons, and Neutrons
they are protons, electrons and neutrons
H Ra this is the symbol if you synthesize this atom, your answer would be 14 3 5
Protons neutrons and electrons
The oxidation number of the central atom Al in AlF6^3- is +3. This is because each F atom contributes a -1 charge, and the overall charge of the complex ion is -3, so the Al atom must have a +3 oxidation state to balance it out.
The three main parts to an atom would be Protons, Electrons and Neutrons. Then you have sub-atomic particles, Sub - Neutrons, so on so forth
