The diffirentiate of atomic mass and atomic number?
Atomic mass is the total mass of an atom, which includes the mass of protons, neutrons, and electrons. Atomic number is the number of protons in the nucleus of an atom. Atomic mass is the sum of the number of protons and neutrons, while atomic number is the number of protons only.
Why is the atomc mass not a whole number?
The atomic mass listed on the periodic table is a weighted average of all the known isotopes of an element. Since isotopes have different masses based on the number of neutrons they contain, the average atomic mass is not a whole number. It accounts for the abundance of each isotope in nature.
What is the atomic mass of an element?
The atomic mass of an element is the average mass of an atom of that element, taking into account the different isotopes and their relative abundances. It is typically expressed in atomic mass units (u) and can be found on the periodic table below the element's symbol.
What part of the nucleus determine the atomic mass for an element?
The number of protons and neutrons in the nucleus determine the atomic mass for an element. The atomic mass is typically calculated by adding the number of protons and neutrons together.
What is the average atomic mass of element x to the nearest hundredth of an atomic mass unit atomic mass what is atomic mass?
Element does not exist so I have to ignore that part. Atomic mass as it appears on the periodic table is an average mass of gram (weight) per mole of atom (see avagadros number). Furthermore, it is average in the sense that it is weighted based on the percentage of a specific isotope existing (some contain more neutrons than others) with the actual weight of each isotope
The diffirentiate of atomic mass and atomic number?
Atomic mass is the total mass of an atom, which includes the mass of protons, neutrons, and electrons. Atomic number is the number of protons in the nucleus of an atom. Atomic mass is the sum of the number of protons and neutrons, while atomic number is the number of protons only.
Define ion word part in health?
ions are the charges on elements or compounds
Which is not part of John Dalton atomic theory?
Atoms are made up of smaller particles.
What part of the atom contains the least atomic mass?
Electron. Contains basicaly no mass what so ever.
Why is the atomc mass not a whole number?
The atomic mass listed on the periodic table is a weighted average of all the known isotopes of an element. Since isotopes have different masses based on the number of neutrons they contain, the average atomic mass is not a whole number. It accounts for the abundance of each isotope in nature.
What is the atomic mass of an element?
The atomic mass of an element is the average mass of an atom of that element, taking into account the different isotopes and their relative abundances. It is typically expressed in atomic mass units (u) and can be found on the periodic table below the element's symbol.
What part of speech are atomic symbols?
Atomic symbols are considered nouns because they are used to represent specific elements in the periodic table.
How is the mass number different from the atomic number of an atom?
The mass number is the total number of protons and neutrons in the nucleus of an atom, while the atomic number is the number of protons in the nucleus. Mass number determines the atom's mass, while atomic number identifies the element on the periodic table.
What part of the nucleus determine the atomic mass for an element?
The number of protons and neutrons in the nucleus determine the atomic mass for an element. The atomic mass is typically calculated by adding the number of protons and neutrons together.
In the second short period of the Periodic Table what do the elements have in common?
In the second short period of the Periodic Table, elements have the common property of having their valence electrons in the 2s orbital. These elements are categorized as part of Group 2 and have similar chemical properties due to the number of valence electrons they possess.
Can two elements have same atomic number?
No, two elements cannot have the same atomic number. The atomic number is a unique identifier for each element and is determined by the number of protons in the nucleus of the atom. Each element has a distinct number of protons, which gives it a unique atomic number.
Which part of the atom does the atomic mass measure?
The Nucleus contains Protons and Neutrons which comprise practically all the atom's mass.
