is atomic mass a periodic property?

(online definition), then no, electron configuration does not affect atomic mass, electrons alone barely affect atomic mass, so by that definition of periodic property, atomic mass is not a periodic property.

Periodic Trend The atomic radius of atoms generally decreases from left to right across a period. There are some small exceptions, such as the oxygen radius being slightly greater than the nitrogen radius. Within a period, protons are added to the nucleus as electrons are being added to the same principal energy level.

Atomic mass (ma) is the mass of an atom. A single atom has a set number of protons and neutrons, so the mass is unequivocal (won't change) and is the sum of the number of protons and neutrons in the atom. ... Atomic weight is a weighted average of the mass of all the atoms of an element, based on the abundance of isotopes.

The chemical properties of an element, are determined by the number of protons in the nucleus. This number of protons is called the atomic number. The mass of the atom, its atomic mass, depends upon the sum of the number of protons and the number of neutrons present in the nucleus.

Fundamental properties of atoms including atomic number and atomic mass. The atomic number is the number of protons in an atom, and isotopes have the same atomic number but differ in the number of neutrons.

The modern periodic law states that the properties of the elements are a periodic function of their atomic numbers. As the properties of the elements are dependent upon the atomic number we can say that these are dependent upon the electronic configuration of the elements.

Atomic mass is the weighted average mass of an atom of an element based on the relative natural abundance of that element's isotopes. The mass number is a count of the total number of protons and neutrons in an atom's nucleus.

Answer: When atomic mass is defined in terms of gram it is known as gram atomic mass. When molecular mass is defined in terms of gram it is known as gram molecular mass. ... Molecular mass in gram is equal to atomic weight of the atom.

A period in the periodic table is a row of chemical elements. ... Each next element in a period has one more proton and is less metallic than its predecessor. Arranged this way, groups of elements in the same column have similar chemical and physical properties, reflecting the periodic law.

Atomic mass is associated with the number of neutrons and protons that are present in a particular nucleus of an element. Atomic number is usually the number of protons present in an element's nucleus. ... Isotopes only share the same atomic number.

Major periodic trends include: electronegativity , ionization energy , electron affinity , atomic radius , melting point, and metallic character . Periodic trends, arising from the arrangement of the periodic table, provide chemists with an invaluable tool to quickly predict an element's properties.

The atomic mass is useful in chemistry when it is paired with the mole concept: the atomic mass of an element, measured in amu, is the same as the mass in grams of one mole of an element. ... The modern periodic table is arranged in order of increasing atomic number instead.

All elements have certain characteristics that are summarized on the periodic table. These characteristics include the element's symbol, atomic number, and atomic mass. You will learn how the number of protons in an atom relates to an element's atomic number, and explore how isotopes affect the atomic mass.

Atomic Mass. Mass is a basic physical property of matter. The mass of an atom or a molecule is referred to as the atomic mass. The atomic mass is used to find the average mass of elements and molecules and to solve stoichiometry problems.

Atomic mass is associated with the number of neutrons and protons that are present in a particular nucleus of an element. Atomic number is usually the number of protons present in an element's nucleus. It is the average weight of an element. ... These are some differences between atomic mass and atomic number.

In the modern periodic table, the elements are arranged according to their atomic number - not their relative atomic mass . ... rows, called periods , in order of increasing atomic number. vertical columns, called groups , where the elements have similar properties.
