What is the biggest and jump in atomic weights between consecutive elements on the periodic table Give the pair of elements and the difference in their relative atomic weights?
The largest jump in atomic weights between consecutive elements on the periodic table occurs between oxygen (atomic weight ~16.00) and potassium (atomic weight ~39.10), with a difference of approximately 23.10. This significant increase is due to the transition from lighter elements in the second period to heavier elements in the fourth period.
Can you find any cases in the first 90 elements in which consecutive elements do not have increasing atomic weights?
Yes, in the first 90 elements of the periodic table, there are cases where consecutive elements do not have increasing atomic weights. For example, between lithium (Li) with an atomic weight of 6.94 and beryllium (Be) with an atomic weight of 9.01, the atomic weight decreases instead of increasing.
What elements did John Dalton discover the atomic weights of?
John Dalton determined the atomic weights of several elements, including hydrogen, oxygen, carbon, nitrogen, and sulfur, among others. He used hydrogen as the reference point with an atomic weight of 1, assigning relative weights to other elements based on their combinations with hydrogen. Dalton's work laid the foundation for the modern understanding of atomic theory and the relative weights of elements. His findings were crucial in advancing the field of chemistry in the early 19th century.
What tells you how heavy an elements atoms are compared with atoms of other elements?
the atomic weights on the periodic table
What is the biggest jump in atomic weights between consecutive elements?
The biggest jump in atomic weights between consecutive elements occurs between hydrogen (H) and helium (He). Hydrogen has an atomic weight of approximately 1, while helium has an atomic weight of approximately 4. This increase of 3 atomic mass units represents the largest jump between consecutive elements on the periodic table.
Who was the first scientist to determine atomic weights for elements?
The first scientist to determine atomic weights for elements was John Dalton, an English chemist and physicist.

Yes, in the first 90 elements of the periodic table, there are cases where consecutive elements do not have increasing atomic weights. For example, between lithium (Li) with an atomic weight of 6.94 and beryllium (Be) with an atomic weight of 9.01, the atomic weight decreases instead of increasing.
What is the sum of atomic mass?
I suppose that you think to atomic weights (not mass) of chemical elements and the molecular mass.

Base weight a system of comparing atomic weights to carbon is it true or false?
True. The unit for the atomic weights of chemical elements is the relative atomic mass unit (1/12 from the atomic mass of the isotope 12C). Note that atomic weights is used for elements and atomic mass for isotopes.
What tells you how heavy an elements atoms are compared with atoms of other elements?
the atomic weights on the periodic table
What tells you how heavy elements atoms are compared with atoms of other elements?
the atomic weights on the Periodic Table
How are chemicals related to atomic mass?
The molar mass of a compound is the sum of atomic weights of the contained elements in the molecule.The expression atomic weight is correct for elements; for isotopes is correct atomic mass.
The atomic weights of the elements contain fractional amounts because?
all of the above
Arranged the elements in the periodic table according to increase in atomic weights?
Mendeleev.
What is the biggest jump in atomic weights between consecutive elements?
The biggest jump in atomic weights between consecutive elements occurs between hydrogen (H) and helium (He). Hydrogen has an atomic weight of approximately 1, while helium has an atomic weight of approximately 4. This increase of 3 atomic mass units represents the largest jump between consecutive elements on the periodic table.
Why it is necessary to introduce amu unit?
The atomic mass unit is necessary to evaluate the atomic weights of chemical elements (or atomic masses of isotopes).
