p diddy's number
P stands for Phosphorus. It is in P group. Atomic number is 15.
no number does begin with P...but the first cardinal number to use the letter P is Septillion
As an algebraic expression, six less than a number p is simply: p-6
No, it is not.Incidentally, is a number p is prime then its 2 factors are 1 and p. Their sum is p+1.If p is a perfect number then this sum must be 2p.That is, p+1 = 2p or p = 1.But 1 is not a prime. So no prime can be a perfect number and since 13 is prime, it cannot be a perfect number.
p/q form of the number is 0.3 is: (A) (B)
The mass number of an isotope is the number of neutrons and protons in the isotope, let this be p +n = (mass number). To find the number of neutrons you need the atomic number (number of protons), let this be p. You then subtract the two: mass number - atomic number = no. of neutrons p + n - p = no. of neutrons = n
p + 21.
The answer depends on p. If p is rational then it is, if p is not rational then it is not.
Atomic number for p is 15. atomic mass for p is 31.
A square of any prime number, p has exactly three factors. They are 1, p and p^2.
It depends on the value of p.
