True or False? On a periodic table, the average atomic mass is located in the top right corner on any element.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The average atomic mass is not located in the top right corner on any element on the periodic table. The top right corner of each element's square on the periodic table usually contains the element's atomic number and symbol. The average atomic mass can be found below the element's symbol or in a separate box near the element's square.Rate this question:

Fill in the blank. The element, Lithium (Li) has an average atomic mass of. Hint- (Like you would see it on a periodic table)
Correct Answer
6.9
6.94
6.941
7Explanation
The average atomic mass of the element Lithium (Li) can be found on a periodic table. The options given are 6.9, 6.94, 6.941, and 7. These numbers represent the average atomic masses of Lithium with different levels of precision. The correct answer could be any of the options, as it depends on the level of precision required.Rate this question:

Selection witch ones are the corect anwers. Witch of these answers are found in an atom?
- A.
Proton
- B.
Citron
- C.
Valence Neutrons
- D.
Valence Electrons
- E.
Isotopes
- F.
All of the above.
Correct Answer(s)
A. Proton
D. Valence Electrons
E. IsotopesExplanation
Protons are found in an atom and are positively charged particles located in the nucleus. Valence electrons are also found in an atom and are the electrons in the outermost energy level of an atom. Isotopes are variations of an element with the same number of protons but different numbers of neutrons. Therefore, the correct answers are Proton, Valence Electrons, and Isotopes.Rate this question:

Please anwer this question. What are Isotopes?
- A.
The number in the top right corner of an element
- B.
They are variants of atoms of a particular chemical element
- C.
Can be found by adding the average atomic mass by the atomic number
- D.
All of the above.
Correct Answer
B. They are variants of atoms of a particular chemical elementExplanation
Isotopes are variants of atoms of a particular chemical element. Each isotope of an element has the same number of protons but a different number of neutrons in its nucleus. This results in isotopes having slightly different atomic masses. The number in the top right corner of an element on the periodic table represents the average atomic mass, which takes into account the different isotopes and their relative abundances. Therefore, all of the above options are correct explanations for what isotopes are.Rate this question:
