Probably.
This has not been proved for all even numbers, but no-one has yet found an even number that can not be made this way.
the answer would be in the negatives.Since your stateing a question i do not know what the answer would be because you didnt state one.
1. The difference of two numbers are the numbers between them. The difference is found by subtracting the smaller number from the larger. In this case, 2 is subtracted from 3 (3-2) with a difference of 1. 3-2=1
The atomic mass number is the sum of the protons and neutrons of an element. The protons are given by the atomic number, so the neutrons can be found by subtracting the mass number by the atomic number. Both the mass and atomic numbers can be found on the periodic table.
The proton number is the same as the atomic number of the element, which can be found from the periodic table. The number of neutrons can be found by subtracting the atomic number from the mass number given for the isotope in question.
All real numbers.
Difference between two numbers is found by subtracting the first from the second. Start with 5 apples, End with 7 apples. The difference is 2 apples.
This is a good question, alas, it is unanswerable, as numbers are infinite and more primes are being found every day.
Numbers to the right of zero on a number line are positive numbers; to the left are the negative numbers.
The length can be found by taking the larger number in the frequency group and subtracting it to find the range.
subract the number from the number, simple, at least that is what i found
-3 is one example.
Since chromium has an atomic number of 24, each atom of it contains 24 protons. The number of neutrons can be found by subtracting the atomic number from the mass number. Thus, chromium-63 has 39 electrons.
