True? I really don’t know but ones someone
I say climate, because a climate will prevent most areas and if it was a area or as I call a condition it would stay shorter?!.
Answer: mass
Explanation: the protons and neutrons make up the nucleus and nearly the entire mass of the atom
Sr will always have 38 protons because that is its atomic number. Normally Sr has 38 protons and 49 neutrons yielding an atomic mass of 87. unless you are dealing with an isotope of Strontium in which 3 additional neutrons would give you the 53 neutrons in your answer, (38p, 52n).
Argon monatomic in nature because it is a noble gas and has completely filled shells and thus does not form a bond with other elements.
