How are alpha particles written?
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).
How many isotopes does helium have?
Helium 3 and helium 4 are naturally occurring isotopes 5 thru 10 are exotic isotopes.
What is the helium weight?
Helium's atomic weight = 4 amu
What is the atomic mass of helium if you know that 2.5 mo of helium has a mass of 10 grams?
Atomic mass = weight in gram / moles = 10 / 2.5 = 4 amu
What does the 4 in 42He represents?
The "4" in ( ^4\text{He} ) represents the mass number of the helium isotope, which is the total number of protons and neutrons in its nucleus. Helium-4 specifically has 2 protons and 2 neutrons, making it the most common and stable isotope of helium. In this notation, the "He" stands for helium, while the superscript "4" indicates its atomic mass.

How do you write 4 squared?
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

How do you display the power of 4 symbol like you do with the 3 and 2?
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.
Are helium-4 and helium-3 istopes?
Yes, they are isotopes of helium
Is an exponent a subscript or superscript?
It would be a superscript.
