What is the charge on an electrically neutral atom of hydrogen?. . A. 1. . B. 0. . C. +1. . D. +2.
2 answers:
When the number of electron and number of protons are equal in the atom then the atom is said to be an electrically neutral atom. The loss of electron will result in the formation of cation and the atom will possess positive charge which is equal to the number of electrons lost whereas the gain of electron will result in the formation of anion and the atom will possess negative charge which is equal to the number of electrons gained.
The electrically neutral atom have 0 charge as the number of protons and electrons are equal.
For electrically neutral atom of hydrogen, the number of electron =1 and the number of proton = 1.
Hence, the charge on an electrically neutral atom of hydrogen is 0.

Answer:
<em>Option C: 4.54 x </em><em> KJ/mol of nuclei</em>
<em>Note: </em>Here in this question option C is not correctly put. It is 4.54 x rather than 4.54 x
.
Explanation:
If mass defect is known, then nuclear binding energy can easily be calculated, here's how:
First step is to convert that mass defect into kg.
Mass defect = 5.0446 amu
Mass defect = 5.0466 x 1.6606 x
Because 1 amu = 1.6606 x Kg.
<em>Mass defect = 8.383 x </em><em> kg.</em>
Now, we need to find out it's energy equivalent by using following equation:
Using the equation E = mc²:
where c= 3.00 x m/s²
E = (8.383 x ) x (3.00 x
)²
E = 7.54 x J this energy is in Joules but nuclear binding energy is usually expressed in KJ/mol of nuclei. Let's convert it:
(7.54 x Joule/nucleus)x(1 kJ/1000 Joule)x(6.022 x
nuclei/mol) =
<em>4.54 x </em><em> kJ/mol of nuclei .</em>
E = <em>4.54 x </em><em> kJ/mol of nuclei .</em> So, this is the nuclear binding energy of that atom, which is option C.
<em>Note:</em> Here in this question option C is not correctly put. It is 4.54 x rather than 4.54 x
