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 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.
How to find the total electron in element?
To find the total number of electrons in an element, first you need to look up the element's atomic number. That number tells you how many protons are in the element. Then, look up the net charge of the element. The number of protons subtracted by the elements net charge will give you the number of its electrons.
Total number of protons and neutrons in the atom is?
The total number of neutrons in an atom is known as its atomic mass. The sum of all the atomic weights of isotopes of a particular element is known as an element's atomic weight. Atomic weights are decimal numbers for this reason.
What is the total number of neutrons represented by?
To determine the total number of neutrons in an atom, subtract the atomic number (which represents the number of protons) from the atomic mass number (the total number of protons and neutrons). For example, if an element has an atomic mass of 12 and an atomic number of 6, it has 6 neutrons (12 - 6 = 6). If you provide the specific element or isotope, I can give you the exact number of neutrons.
Distinguish between the atomic number and mass number of an element?
The atomic number of an element is the number of protons in the nucleus of each atom of the element. Mass number is a property of a particular isotope of the element rather than of the element itself: The mass number is the sum of the numbers of protons and neutrons in the nucleus of each atom of the isotope.
What is the difference between the atomic number and the atomic mass?
The atomic number represents the number of protons in an atom's nucleus, determining its chemical properties and element identity. Atomic mass is the total mass of an atom, which includes the sum of its protons, neutrons, and electrons.
Do the protons or neutrons Equal the atomic number?
The atomic number of an element is defined by the number of protons in its nucleus. Therefore, protons equal the atomic number, while neutrons do not; instead, the number of neutrons can vary among isotopes of the same element. The atomic number determines the element's identity, whereas the total number of nucleons (protons and neutrons) gives the atomic mass.
What tells you the number of Atoms in of an element?
It is about the atomic numbers. The total of protons.
What is the atomic number in O2?
The atomic number of an element refers to the number of protons in its nucleus. For oxygen (O), the atomic number is 8. So in O2 (oxygen molecule), each oxygen atom contributes its atomic number (8) to the total atomic number for the molecule.
