Oh, dude, let me tell you, there are like a hundred 7's from 1 to 1000. I mean, if you want to get super technical, you can count them all out, but like, who has time for that? Just trust me on this one, there are around a hundred of those lucky number 7's hanging out in that range.
Taking every number from 1 to 1000 inclusive, the number of digit 7s in the list totals 300.
There can be a maximum of 2 electrons in the 7s orbital, following the Pauli exclusion principle which states that each orbital can hold a maximum of 2 electrons with opposite spins.
5.28751 7s equals 37.
8 / 7 in long division is however many 7s go into 8. so there's 1x 7 in 8 with 1 remainder. For this example, assume every number beyond is a 10, multiplied by the remainder. so, it'd be 7s into 10, which is 1 again. Then 7s into 30, which is 4. Then 7s into 20, which is 2. Then 7s into 60, which 8. Then 7s into 40, which is 5. Then 7s into 50, which is 7. And this is a reoccuring number, making it 1.142857142857 and so on.
There is only one orbital in the 7s sublevel. The "7" corresponds to the principal quantum number and "s" indicates the sublevel shape, which is spherical.
7.143, approximately. 50 ÷ 7 = 7 with remainder 1
