Answer:
7 orbitals
Explanation:
An f sublevel has 7 orbitals
Explanation:
(a) mass number = atomic number + number of neutrons
(the atomic number is the number of protons of an element)
mass number of A = 11 + 12 = 23
mass number of B = 17 + 18 = 35
(b) +1 and -1, respectively
(c) A+ + B- → AB (the first plus sign and the minus sign are superscripts)
I believe the correct answer would be "neutron star"
Strontium and chlorine react to form strontium chloride with the formula SrCl2.
That would be 'ionises' .
