4He or He4.
4 stands for the mass number of Helium
Mass number = number of protons + number of neutrons
Since the atomic number or number of protons in helium is 2, the number of neutrons in He-4 is also 2.
The noble gas notation starts for elements after helium. Helium has no noble gas notation. Its electronic configuration is 1s2
An alpha particle can be written as ¸He«+ (Sorry, but it will not print properly on this answer page. The notation should be a superscript 4 over a subscript 2, followed by He, and then a superscript 2 over a subscript 2, followed by a superscript + sign).
Helium 3 and helium 4 are naturally occurring isotopes 5 thru 10 are exotic isotopes.
Helium's atomic weight = 4 amu
Atomic mass = weight in gram / moles = 10 / 2.5 = 4 amu
It is 1s2 (2 in superscript).
The noble gas notation starts for elements after helium. Helium has no noble gas notation. Its electronic configuration is 1s2
No, it's a particle. Often written a it is the least penetrating radiation not able to penetrate a pice of paper. Consists of a helium nucleus superscript 4 over sub script 2 He
An alpha particle can be written as ¸He«+ (Sorry, but it will not print properly on this answer page. The notation should be a superscript 4 over a subscript 2, followed by He, and then a superscript 2 over a subscript 2, followed by a superscript + sign).
You can write 4 squared by writing a 2 in superscript after the number 4. (42) If you can't use superscript because you're using a computer program that does not allow it writing 4^2 would be an acceptable substitute. In Microsoft word you can activate superscript by pressing Ctrl+Shift+Equals
Change the font style of the 4 to 'superscript'
what is the anthomny for superscript
helium = 4 molar mass
just like you would with the 2 and 3. it is just in superscript. you can have any power, it is just always a superscript.
Yes, they are isotopes of helium
It would be a superscript.
Helium-4 has 2 electrons.
