Homework Answers
Al and B are in period less than 3
So, they will not have any d electrons.
So, both have 0 d electrons.
Br and Kr are in p block and in same period.
They will have same number of d electrons.
Pd and Ag are in d block.
No 2 d block neutral elements can have same number of d electrons.
Cu and Zn are in d block.
No 2 d block neutral elements can have same number of d electrons.

Which of the following statements about hybridization are true? Select all that apply: Hybrid orbitals exist in isolated atoms. Hybrid orbitals within the same atom have the same energy and shape. Hybrid orbitals are described mathematically as a linear combination of atomic orbitals. An atom can have both hybridized and unhybridized orbitals at the same time.

II. Isotopes Atoms of a given element all have the same number of protons and electrons, but can have different numbers of neutrons. Versions of the same element with differing numbers of neutrons are call isotopes. The symbol for an isotope is AX Where: A is the mass number (number of protons plus neutrons) Z is the atomic number (number of protons) X is the symbol for the element 2.

20.) Using orbital diagrams, determine the number of unpaired electrons in each of the following atoms. Start with the noble-gas core designation in the first box and then enter electron arrows. Enter your answer using UP to indicate an upwards pointing arrow, DOWN to indicate a downwards pointing arrow, UP/DOWN to indicate two arrows(electrons) in the same orbital, and BLANK to indicate no arrows. Designate unpaired electrons as UP arrows and keep all unpaired electrons and empty orbitals in the...
