Bismuth will not have the same number of valence electrons.
What is valence electrons?
Valence electrons are those that are found in an atom's outermost electron shell. These electrons are involved in bonds and reactions because they are the farthest from the nucleus and as a result are less tightly held by the atom.
This implies that an element's reactivity, electronegativity, and the number of bonds it may form are all dependent on the number of valence electrons it possesses. The ability of an element to create bonds with other atoms is referred to as valence.
The number of hydrogen atoms an element can bond to (which is determined by how many valence electrons are available for bonding) has historically been used to determine an element's valence.
Therefore, Bismuth will not have the same number of valence electrons.

Answer: The correct answer is bismuth.
Solution:
Bismuth is the member of group 15 of the periodic table.
Bismuth contains five valence electrons in its valence shell. Which can be seen from its electronic configuration:
Where as other three elements are the members of group 14 of the periodic table with three valence electrons in their respective valence shells.

The answer there is 12.3 kJ. First you have to calculate the amount of heat released (n) based on the given. Just multiply 36.8 grams of water to a mole of water per 18.015 grams, which will give you 2.04 moles of H2O. Using the formula heat released (q) = number for moles of the substance (n) multiplied to the molar enthalpy of fusion of the substance (H), you will have the (2.04 mole)(-6.01 kJ/mole), giving you an answer of -12.3kJ.

(4.32x10^23)/(6.02x10^23) = .703mol Fe
Then multiply moles by its molar mass:
(0.703mol Fe)(55.85g/mol Fe) = 39.24g Fe
