The set of symbols that represents isotopes has been 84/38 M 86/38 M 87/38 M. Thus, option D is correct.
The isotopes are the elements with same atomic number, but different mass number. In an isotope [tex]\rm ^a_bX[/tex], a has been the atomic mass, and b has been the atomic number.
The isotopes will have same value for b, while different values for a.
In the following given sets:
A. 50/19 L 50/20 L 50/21 L
It has same number of mass the atomic number has been different. Thus, the set not represents isotopes.
B. 138/59 Q 133/55 Q 133/54 Q
The given elements, has different atomic number, and different mass number. Thus the set did not represents the isotopes.
C. 91/42 J 92/42 J 93/40 J
The given elements, has different atomic number, and different mass number.Thus the set did not represents the isotopes.
D. 84/38 M 86/38 M 87/38 M
The given set has same atomic number with different mass number.Thus, the set has been the representation of isotopes.
The set of symbols that represents isotopes has been 84/38 M 86/38 M 87/38 M. Thus, option D is correct.

how many valence electrons are in the element gallium? explain how you determined the number.
Gallium has three valence electrons.
Elements in the periodic table are classified into groups and periods. Elements in a given group have the same number of valence electrons on their outermost shell while the elements in a period have the same number of shells.
All the elements in group 13 have three electrons in their outermost shell. Gallium is an element of group 13. This means that gallium also has three electrons in its outermost shell(valence electrons).
Learn more: https://brainly.com/question/2673886
Gallium has 3 valence electrons (1 electron in the 4p orbital and 2 electrons in the 4s orbital) because the valence electrons are those located in the outermost energy level of an atom.
Gallium has an atomic number of 31, which means it has 31 electrons in total. The electron configuration of gallium can be represented as [Ar] 3d¹⁰ 4s² 4p¹.
Within the n=4 shell, gallium has electrons in the 4s and 4p orbitals. The 4s orbital can hold a maximum of 2 electrons, while the 4p orbital can hold a maximum of 6 electrons. In the case of gallium, there is 1 electron in the 4p orbital.

Two objects are moving in a straight line. One object has a faster speed than the other. They both have constant speeds (speed is not changing). Is either object accelerating?
Answer:
No
Explanation:
Acceleration refers to the increase in speed over time. Since both of the objects are moving at a constant speed (so the speed is not changing) neither are accelerating, because acceleration requires a positive change in speed.
They may be moving at different speeds, one faster than the other, but neither are changing their own speed so neither are accelerating.

Which element has an atomic mass of 106.42?
Answer:
carbon
Explanation:
The element which has atomic mass of 106.42 is carbon as per the existing isotopes.
What is an element?
It is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.
