What is the atomic number if the first element to start filling a d sublevel?
The d suborbitals begin at period 4, but the d-sublevel is actually 3d. The first element is scandium, which has the atomic number of 21.
How many valence electrons would an element with atomic number 56 have?
The element with atomic number 56 is barium, a group 2 alkaline earth metal. Its atoms have two valence electrons in the 6s sublevel.
Is the atomic number how many atoms are in the element?
Not necessarily. The atomic number is the same amount as the protons found in a certain element. remember that the number of protons are equal to the number of electrons as well. EX - Calcium's atomic number is 20 so therefore there are 20 protons and 20 electrons in the element. The atomic number also helps you find any valence electrons EX- oxygen's atomic number is 8 so you have 2 electrons filling the 1st orbital and 6 filling the 2 orbital. but the 2nd orbital is supposed to have 8 electron so there are 6 valence electrons.
What information is given by the angular momentum quantum number?
Each atomic orbital is designated by the principal quantum number followed by the letter of the sublevel. -for more information see..."Modern Chemistry" text book Pg.108 3rd and 4th paragraph.
