Which is a factor in determining the average atomic mass of an element?
The two main factors in determining the average atomic mass of an element are:the isotopic composition of the element (the fraction of each isotope)the atomic mass of each isotope
Which main part of an atom determines the atomic number of an element?
The number of protons, which are found in the nucleus of an atom.
What four pieces of information about each element is found on the periodic table?
Well the four main types really go down to the Atomic Number, Atomic Mass, The Chemical/Atomic symbol, and the elements name of course. But different tables vary.
How are the atomic mass unit and the atomic weight related?
The mass number is the total amount of protons and neutrons in an atom (the number of protons is the same as the number of electrons) The atomic number is the number of protons (or electrons) in an atom. To find out the number of neutrons in an atom, you need to take the atomic number from the mass number An atom is normally written like this: Mass number Ca Atomic number The Mass number can be written as (A) and the atomic number can be writtens as (Z)
Why is atomic mass of an element an average mass?
The Atomic Mass of an element is the numerical average of all the masses of the naturally occurring isotopes of that element proportionately. Man made elements do not count in supposedly. IE: If we have an element with atomic weight 100 and we have an isotope of that element with atomic weight 102 and if they occurred equally in nature then the Atomic Mass would be 101.

What 4 things are included about each element in the periodic table?
The four main things included about each element in the periodic table are its chemical symbol, atomic number, atomic mass, and the element's name. These provide key information about the element's identity, structure, and properties.
Who are the early contributors to the development of alphabets?
The Phoenicians were the main early contributors.

What is the constituent element of calcium?
The main constituent element of calcium is calcium itself, which is a chemical element with the symbol Ca and atomic number 20.
What is One of the two main contributors to the double helix model of DNA nucleotides?
The two main contributors areJames WatsonFrancis Crick
Is it true that isotopes have the same atomic weight?
Atomic mass is the mass of an atom Atomic weight is the average mass of an atom based on the abundance of different isotopes No, because mass and weight are two different things. Weight is gravitational pull, while mass is how much matter there is in an object.
The main difference between the more than 100 different element is what?
The number of electrons each element contains on its shells outside the nucleus.
What is the energy level for atomic weight 11?
Atomic weight 11 corresponds to the element sodium (Na), which has an atomic number of 11. In terms of energy levels, sodium has three main electron shells: the first shell can hold up to 2 electrons, the second can hold 8, and the third shell has 1 electron. This configuration reflects its position in the periodic table and contributes to its chemical properties, particularly its reactivity and tendency to lose that single outer electron to achieve a stable electron configuration.
