Density decreases that's why ice floats on water because it's less dense than water.
Hey there!:
density = mass / volume
d = 57.2 / 33.8
d = 1.692 g/mL
hope this helps!
thats kinda hot not even gon'
Are you asking for a specific atom or just the general definition?
The general definition of alpha decay is the loss of two protons and two neutrons from a nucleus. (Also equal to a helium atom!) This decreases the total mass number by 4 and the atomic number by 2.
The answers would be
1.b
2.c
3.a
