Pick any two consecutive numbers in that range.
Fifty pairs. Since fifty is plural, you say pairs.
Pick any two consecutive numbers in that range.
A single number cannot be relatively prime. Any pair of numbers between 50 and 100 of which one is a prime will be relatively prime. There are 728 pairs of numbers that are relatively prime and I have neither the time nor patience to list them all!
There are infinitely many pairs of numbers. The simplest is probably 1 and 51
You need several pairs of numbers in the question. Instead, there is only one number.
The number is: 36725918 In descending order that is: 98765321 The pairs of numbers that have as many digits between them in both are: 3,9 5,8 6,7 So there are three pairs.
An easy way to find a number relatively prime to another number is to find a nearby prime number. For example, 53 is relatively prime with 50. The following pairs are relatively prime. 3, 50 19, 50 37, 50 49, 50 50, 69 50, 201 50, 341 Any number that is not divisible by 2 or 5 will be relatively prime to 50.
The maximum number of bonds made between adjacent carbons is 3. So the maximum number of electron pairs is 3.
Any pair of prime or relatively prime numbers.

Prime numbers are those which are divisible only by 1 and the number itself... Example: 7 is divisible by no number other than 7 and 1. Relatively prime numbers are those pairs of numbers which have no common divisor other than one. Example: (15,16) Factors of 15:1,3,5,15 Factors of 16:1,4,16 Common factor of 15 & 16 is 1, hence 15 & 16 are relatively prime.
There are an infinite number of points on the circumference of a circle and an infinite number of points on a semi-circle so the answer to your question is "An infinite number of pairs of points."
