Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
What subatomic particles are used to calculate the mass of an atom?
Hey! The excepted banacular is gay. Don't call them atoms that's just mean.
Atomic mass of an atom is determined by the weight of?
The atomic mass of an atom is determined by the total number of protons and neutrons in its nucleus. Protons and neutrons contribute to the majority of an atom's mass, electrons have negligible mass in comparison. The atomic mass unit (amu) is used to express atomic mass, with 1 amu approximately equal to the mass of a proton or neutron.
Which term is used to describe the way the mass of subatomic particles is described?
Atomic Mass units =]
What is 1amu?
1 amu (atomic mass unit) is a unit of mass equal to one twelfth of the mass of a carbon-12 atom. It is used to express the mass of atomic and subatomic particles.
Si units used for the masses of atomic particles?
The atomic mass unit (u) or unified atomic mass unit (amu) is the standard unit used to measure the masses of atomic particles such as protons, neutrons, and electrons. 1 atomic mass unit is defined as 1/12th of the mass of a single carbon-12 atom.
Can the mass number be used to determine the number of electrons in an atom?
No, the mass number (number of protons and neutrons) cannot be used to determine the number of electrons in an atom. The number of electrons in an atom is determined by the number of protons in the nucleus, which is the atomic number. Electrons are equal in number to protons in a neutral atom.
What is the mass of the atom is so small that there is a measure calles the atomic?
The mass of an atom is so small that there is a unit called the atomic mass unit (amu) used to express it. One atomic mass unit is roughly equal to the mass of a proton or neutron, which are the subatomic particles found in the nucleus of an atom. This unit is convenient for expressing the mass of atoms without dealing with very small numbers.
Can the mass number of an element be used to determine the number of electrons in an atom?
No, the mass number of an element represents the total number of protons and neutrons in the nucleus, but it does not provide information about the number of electrons. The number of electrons in a neutral atom is equal to the number of protons in the nucleus.
Mass number used to calculate the number of?
The mass number is used to calculate the number of nucleons in an atom. It represents the sum of protons and neutrons in the nucleus of an atom. By knowing the mass number, one can determine the approximate atomic mass of the atom.
What determines the atomic mass of an element?
The atomic weight of an atom depends on the number of protons and neutrons in one atom of the element, and is usually the average mass of all the known natural isotopes of the element. The atomic weight refers to the force of gravity on one atom of the element.After the IUPAC rules the atomic mass is a term used only for the mass of isotopes; and the atomic weight is the term used for an element.The atomic weight of an atom is determined by the mass of its constituent particles, the protons, electrons, and neutrons. In practice, however, the electrons are so much smaller than the protons and neutrons, and the neutrons are close enough to the mass of the protons, that it is common to say that the atomic weight is the number of protons plus the number of neutrons. This is not exact, however, and the periodic table reflects this.
Why do you think Thomson hypothesized that electrons must come from inside an atom?
Thomson had two pieces of evidence: 1- No matter what metal he used for the disk, the particles produced were indentical. 2- The particles had about 1/2000 the mass of a hydrogen, the lightest atom. These experiments provided the first evidence that atoms are made of even smaller particles.
