The atomic mass of an element is defined as the weighted average mass of that element's?
For the chemical elements the correct expression is atomic weight.This value is the weighted average mass of the natural isotopes of this element.
What is the average atomic mass compared to atomic mass?
Atomic mass is the number of protons and neutrons in an atom.
Defined what an element is?
The atomic number, the number of protons
What does 4.00 stand for in the periodic table?
In the periodic table, the number 4.00 typically refers to the atomic mass of an element. It represents the average mass of one atom of that element relative to the mass of a carbon-12 atom which is arbitrarily defined as 12.
Atom of an element that differs in the number of nuetrons compared with other atoms of the same element?
Is called an Isotope.
The atomic mass of an element is defined as the weighted average mass of that element's?
For the chemical elements the correct expression is atomic weight.This value is the weighted average mass of the natural isotopes of this element.
Is lavoisier correct to refer to charcoal as an element?
No as charcoal consists on average of only 85-98% carbon, an element is defined as a pure substance.
What is the average atomic mass compared to atomic mass?
Atomic mass is the number of protons and neutrons in an atom.
An atom is defined as the?
smallest particle of an element that retains the properties of that element.
Can An element be defined by the number of protons in the nucleus?
no
Why do you think changing the number of neutrons does not create a new element?
Because an element is defined by it's atomic number. Which is defined by the number of protons found in atom. Adding a neutron creates an isotope of an element.

Atom of same element that differs in numbers of neutrons compared to other atoms of the element?
Isotope
What is the average mass of the isotope of an element?
the average mass numbers of the isotopes of an element
What number is each element defined by?
Its atomic number, equal to the number of protons in each atom of the element.
Can form can be defined as the constructive or organizing element in music?
True
