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.
What is the mass of an element?
The mass of an element is determined by the total number of protons and neutrons in its nucleus. This mass is typically measured in atomic mass units (amu) and is an average of all the naturally occurring isotopes of that element.
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.
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 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 is the mass of an element?
The mass of an element is determined by the total number of protons and neutrons in its nucleus. This mass is typically measured in atomic mass units (amu) and is an average of all the naturally occurring isotopes of that element.
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.
What is a atomic number in a element?
The atomic number of an element refers to the number of protons in the nucleus of the atom of that element, and is unique to each element. The atomic weight is the weight of an atom of the element compared with the weight of a single proton, and consists of number of protons and neutrons in the nucleus of the atom of that element, and different atoms of the same element can have different numbers of neutrons, and therefore more than one atomic weight: it is usually given as an average. the atomic number on an element is simply the number of protons and electrons in the element. however, it is not the total number of them.
