What makes up the weight an atom or molecule?
The number of protons and neutrons controls the weight of an atom.
What particle control the 'weight' of an atom?
The weight of an atom is primarily controlled by the total number of protons and neutrons in its nucleus. Protons and neutrons have approximately the same weight, while electrons have negligible mass compared to protons and neutrons.
What makes up the atomic weight of an atom?
The total weight of the protons and the neutrons.
Atomic weight is equal to the?
Atomic weight/ mass = number of protons + number of neutrons
What is the weight of the atom if an atom has 9 protons?
The weight (mass) of an atom with 9 protons will vary depending on the number of neutrons. 9 protons defines the atom as fluorine (F), and it can have 10 protons, making the mass 19 amu, or it can have a mass of 14 amu up to 31 amu, but the only stable isotope is the one with a weight (atomic mass) of 19 amu.
What makes up the weight an atom or molecule?
The number of protons and neutrons controls the weight of an atom.
What is chemical atomic weight?
Atomic weight = Weight of protons + Weight of neutrons
Is the atomic weight of an element is equal to the number of protons minus the number of neutrons?
No, the atomic weight of an element is not equal to the number of protons minus the number of neutrons. Atomic weight is the average weight of an element's isotopes taking into account their abundance, which includes the sum of the protons and neutrons in the nucleus.
Do protons electons and neutrons differ in mass?
As I remember neutrons and protons weight something similar, electrons have a far smaller mass which is negligable in comparison to the weight of protons.
Does the number of protons in an atom of an element always equal its atomic weight?
atomic weight = mass of protons + mass of neutrons
What particle control the 'weight' of an atom?
The weight of an atom is primarily controlled by the total number of protons and neutrons in its nucleus. Protons and neutrons have approximately the same weight, while electrons have negligible mass compared to protons and neutrons.
How can you find out the number of neutrons in an atoms nucleus?
By the process of elimination. For example, The atomic weight of an atom is just the number of its protons, and the atomic mass is the total weight of protons and neutrons in the atom. So, the atomic weight of Oxygen is 8(protons) and the atomic mass is 16(protons + neutrons) so we can tell that there are 8 protons and 8 neutrons.
Is the atomic weight the same as the atomic number?
No, the atomic number is the number of protons that an atom contains. Atomic weight is the number of protons and neutrons.
What subatomic particles are almost the same weight?
Protons and neutrons are about the same weight. Electrons are far lighter than either protons or electrons.
What gives an element its atomic weight?
no. of protons
What makes up the atomic weight of an atom?
The total weight of the protons and the neutrons.
How do scientists determine the atomic weight of an element?
they find out the atomic weight by adding the total number of neutrons and protons. for example, helium has a atomic weight of 4 since there are 2 newtons and 2 protons.
