What else can I help you with?
Where are the mass variances in 2 atoms of the same element and why do they occur?
If the chemical element has isotopes, each isotope has a specific and different atomic mass.
What is john Dalton conclusion?
Atoms are made up of the smallest form of matter
Which scientist said each element is made of a different type of atom?
The scientist who proposed that each element is made of a different type of atom is John Dalton. In the early 19th century, Dalton formulated the atomic theory, which stated that matter is composed of indivisible atoms, and each element has atoms that are unique in mass and properties. This foundational idea helped to advance the understanding of chemical reactions and the nature of elements.
Does mole of carbon atoms have a different mass than a mole of sulphur atoms?
Yes. To find out the mass of a mole of atoms of any given element, see the atomic mass given on the periodic table. A mole of carbon atoms has a mass of 12.011 grams. A mole of sulfur atoms has a mass of 32.06 grams.
Do the Empirical formula relates the mass of each element in a compound to the entire mass of the compound?
An empirical formula gives this information indirectly by specifying the ratios of numbers of atoms of each element in a compound to the total number of atoms in a compound. These ratios can then be mathematically converted into the mass ratios specified in the question by using the known atomic weights of each element present: The mass ratio of element "Q" to element "R" is equal to the number ratio multiplied by the ratio of the atomic weight of element Q to that of element R. For example, the number ratio of hydrogen to oxygen in water is 2, but the mass ratio is 2(1.008/15.999) = 0.1260.
How are atomic mass and atomic number different?
Atomic number is the number of protons in the nuclei of the atoms of an element. Atomic number is unique to each element. Atomic Mass is the combined mass of the protons, neutrons, and electrons in an atom of an element.
How are atomic number and atomic mass alike?
Atomic number and atomic mass are not alike. Atomic number is the number of protons in the nuclei of the atoms of an element. Each element has a unique atomic number. Atomic mass is the combined masses of the protons, neutrons, and electrons of the atoms of an element. Individual isotopes of an element have specific mass numbers, which are the sum of the protons and neutrons in the nuclei of the atoms of the isotope.
Tells you the number of atoms in each element?
atomic mass is the answer
The average atomic mass grams shown on the periodic table for each element is also the mass of?
one mole of atoms of the element
Where are the mass variances in 2 atoms of the same element and why do they occur?
If the chemical element has isotopes, each isotope has a specific and different atomic mass.
What is john Dalton conclusion?
Atoms are made up of the smallest form of matter
What are three facts about elements?
Elements are the simplest form of matter and cannot be broken down into simpler substances. Each element is made up of atoms that have a specific number of protons in their nucleus, which determines their unique chemical properties. There are currently 118 known elements, with each element having its own unique symbol on the periodic table.
How many mass units is there if each atom of element X has 13 mass units and each atom of element Z has 31 mass units?
The answer depends on how many atoms of X and Z are found in each molecule of the compound.
What is the relationship between mass number and atomic numbers?
The mass number is the sum of protons and neutrons in an atom's nucleus, while the atomic number is the number of protons in the nucleus. The atomic number uniquely identifies an element, while the mass number helps determine the atom's mass.
Which scientist said each element is made of a different type of atom?
The scientist who proposed that each element is made of a different type of atom is John Dalton. In the early 19th century, Dalton formulated the atomic theory, which stated that matter is composed of indivisible atoms, and each element has atoms that are unique in mass and properties.

Which element in each pair has atoms with a larger atomic mass?
Carbon vs. Oxygen: Oxygen has atoms with a larger atomic mass. Sodium vs. Magnesium: Magnesium has atoms with a larger atomic mass. Phosphorus vs. Sulfur: Sulfur has atoms with a larger atomic mass.
