Where does the weight of the nucleus mostly come from?
The nucleus is made up of protons and neutrons. Most of the elements with low atomic numbers are equally protons and neutrons. However, as elements get heavier they will have more neutrons than protons, and since each weigh the same amount (1 atomic mass unit) these nuclei will get most of their weight from the neutrons.
What is equal to the mass of a proton?
The neutron has about the same mass as the proton, each has a mass a tiny amount greater than 1 AMU (atomic mass unit). The neutron is the smallest bit more massive.The electron has a mass of just a bit over 5/10,000ths of an AMU. Extremely less massive in comparison, isn't it!
What is a particle of atom?
Sub-atomic particle is the proper term to describe your question. We generally know atom construct from proton, neutron and electron while proton is positron and neutron. To even smaller scale, it is the Quark that is the building block of the matter.
What unit of measure would you use to measure the mass of an elephant?
in tons.
What mass of substance is required in grams?
Gram is a unit of measure, for mass.
What contributes to the mass of the atom?
number of protons and number of neutrons
Is a proton the least mass?
In an atom, there are 3 types of particles: protons, neutrons and electrons.Theoretically, protons and neutrons weight 1 Atomic Mass Unit. An electron weights 1/1836 of an Atomic Mass Unit. Therefore, in an atom, electrons weigh the least.
Is the mass of a single electron one mass unit?
No, it's about 1/2000th of an amu (atomic mass unit). Protons and neutrons are 1 amu.
The atomic mass equals what?
In science the basic unit is the atom which is composed of neutrons, protons, and electrons. Electrons are generally considered to small to count as part of the mass. Atomic mass is the sum of neutrons and protons. For example: Oxygen has 6 protons and, in its natural state, 6 neutrons. This means that its atomic mass is 12.
What is the atomic mass unit of protons and neutrons?
atomic number or atomic mass
Atomic mass is equal to what?
atomic mass unit is equal to one-twelfth of the mass of a carbon-12 atomic mass is equal to one-twelfth of the mass of a carbon-12Atomic Mass is equal to the number of protons and neutrons.
What is Atomic Mass unit based on?
The mass of any isotope is based on the mass of an isotope of carbon, which is assigned a mass of 12.
An atom has an atomic mass of 101g and has 57 neutrons what is the atomic number?
If an atom has an atomic mass of 101g and 57 neutrons, then:Atomic Mass = (number of protions) + (number of neutrons) 101 = (X) + (57) or.... (101) - (57) = x 101-57=44 the element that has 44 as its atomic number would be RutheniumAs we know mass of atom is primaril constituted by the neutrons and protons,while the mass of electron is neglegible.Taking mass of proton equal to mass of neutron and both having a unit mass.we can say that mass of an atom is equal to the number of protons and neutrons multiplied with the mass of i proton/neutron.we are given mass of lithium =7=>(no. of neutron + no. of protons)*(mass of 1 proton/neutron)=7=>no. of neutrons + no. of protons *(1)=7=>no. of neutrons=7-no. of protons=>no. of neutrons=7-3 (atomic no=no. of protons)=>no. of neutrons=4
What is the differnece between mass number and atomic number?
Answer 1The mass number of a nuclide is the sum of the mass of the protons and neutrons in the nucleus. Protons and Neutrons have a mass of approximately 1 atomic mass unit (electrons are not included since the mass relative to the mass of a proton and neutron is to small to count in the total mass. The atomic number of an atom corresponds to the number of protons in the nucleus, and that is the difference.Answer 2Mass number is the total number of protons and neutrons in the nucleus of an isotope. Atomic number is the total number of protons in the nucleus of each atom of an element.
Which particles determine the mass of an atom?
The atomic mass unit is defined to be 1/12 of the mass of a carbon-12 atom. Atomic masses can determined by weighing molar amount of an isotope. Absolute masses (in kg) are determined by measuring the amount that charged atoms are deflected by magnets, since if you know the charge you can calculate mass from the amount of deflection.
What unit of measure is used for measuring the mass of an atom?
Protons and neutrons are 17 septillionths of a gram. That is can be written as 0.0000000000000000000000017 or 1.7 times 10 to the -24th power. An electrons mass is too small for scientist to care about.
Relation between subatomic particles and atomic mass unit?
protons and neutrons are subatomic particles and adding the two amounts together gives you the atomic mass unit
