How was the atomic number and the atomic mass determined?
The atomic number of an element is determined by the number of protons in the nucleus, which can be identified through methods like spectroscopy and X-ray diffraction. Atomic mass is determined by the total number of protons and neutrons in the nucleus, which can be calculated based on the element's isotopic composition and their respective masses.
Which of the following determines the identity of an element atomic number mass number atomic mass or overall change?
Atomic number determines the identity of an element. It represents the number of protons in an atom's nucleus, which is unique to each element. Mass number refers to the total number of protons and neutrons in an atom's nucleus, while atomic mass is the average mass of an element's isotopes. Overall charge is determined by the number of protons and electrons in an atom, but it does not uniquely identify the element.
What is a sentence for atomic number?
The atomic number of an element is determined by the number of protons in its nucleus, defining its unique identity among other elements.
What element has the atomic number of 168?
The element with the highest atomic number is Ununoctium (total quantity that has ever existed: three atoms), and its atomic number is 118. Thulium has an atomic weight of 168.9342.
Which best describes the number of neutron in an atom?
The number of neutrons in an atom can be determined by subtracting the atomic number (the number of protons) from the atomic mass number (the total number of protons and neutrons). For example, if an element has an atomic number of 6 (like carbon) and an atomic mass of 12, it has 6 neutrons. Neutrons play a crucial role in the stability of the nucleus and can vary among isotopes of the same element.

Atomic mass is determined by the total number of protons and neutrons in the nucleus, which can be calculated based on the element's isotopic composition and their respective masses.
What determines the atomic number of a substance?
The atomic number is the number of protons in the nucleus of an atom, while the atomic mass is the total mass of the nucleus (both protons and neutrons)
The atomic number is determined by?
The atomic mass is the can be determined by the number of protons in an atom. Remember that a proton has an atomic mas number of 1 AMU (atomic mass unit). (The total mass of an atom is the protons, neutrons and electrons combined.)
What is the total number of an element of a atomic number?
The atomic number is the number of protons (which is the same as the number of electrons) of an element
Which of the following determines the identity of an element atomic number mass number atomic mass or overall change?
Atomic number determines the identity of an element. It represents the number of protons in an atom's nucleus, which is unique to each element. Mass number refers to the total number of protons and neutrons in an atom's nucleus, while atomic mass is the average mass of an element's isotopes. Overall charge is determined by the number of protons and electrons in an atom, but it does not uniquely identify the element.
What is the number of neutons?
The number of neutrons in an atom is determined by subtracting the atomic number (number of protons) from the atomic mass number (total number of protons and neutrons) of that element. For example, carbon has an atomic number of 6 and an atomic mass number of about 12, so it has approximately 6 neutrons (12 - 6 = 6). The exact number of neutrons can vary in isotopes of an element.
What is a sentence for atomic number?
The atomic number of an element is determined by the number of protons in its nucleus, defining its unique identity among other elements.
The atomic number for an element is the total number of subatomic particles?
False; the atomic number is the total number if protons in the nucleus only.
What element has the atomic number of 168?
The element with the highest atomic number is Ununoctium (total quantity that has ever existed: three atoms), and its atomic number is 118. Thulium has an atomic weight of 168.9342.

What is the atomic mass in an element?
The atomic mass in an element is the total number of protons and neutrons in an atom's nucleus.
What determines the properties of elements?
The properties of elements are determined by their atomic structure, including the number of protons, neutrons, and electrons. The arrangement of these particles within an atom influences an element's chemical and physical properties. Characteristics like reactivity, melting point, and conductivity are all tied to an element's atomic structure.
