Answer:
²³⁵₉₂U
Explanation:
The nuclear symbol of the nuclei is ²³⁵₉₂U.
The uranium nuclei has;
mass number = 235
atomic number = 92
To write the structure of the atom;
The subscript before the symbol of the atom is the atomic number
The superscript is the mass number
So;
²³⁵₉₂U is the symbol of the nuclei.
option A.
The number of valence electrons of an element can be determined by the periodic table group (vertical column) in which the element is categorized
The percent of O in Cr₂O₃ : 31.58%
<h3>Further explanation</h3>
Given
Cr = 52.00 amu, O = 16.00 amu
Required
The percent of O
Solution
MW Cr₂O₃ = 2 x Ar Cr + 3 x Ar O
MW Cr₂O₃ = 2.52+3.16
MW Cr₂O₃ =152 amu
Answer:
no
Explanation:
because it will need more energy to move from 5th to 3rd than 4th to 2nd since it is closer to the nucleus
C.temperature and volume is the answer hope these helps you:)
