What has the smaller mass protons electrons or nutrons?
Electrons have the smallest mass compared to protons and neutrons. The mass of a proton is approximately 1836 times greater than the mass of an electron, and the mass of a neutron is slightly greater than that of a proton.
What is the mass of an atom found by?
The mass of an atom is primarily determined by the combined masses of its protons, neutrons, and electrons. Protons and neutrons contribute most of the mass since electrons have negligible mass. The exact mass of an atom can be found by adding up the masses of its protons, neutrons, and electrons.
Why do you say the mass of any element is in the nucleus and you ignore the mass of the electrons?
The mass of any atom is in the nucleus because it contains both protons and neutrons. Protons and neutrons have a significantly greater mass than electrons do, so electrons are ignored when finding the mass of an atom.
How is electrons and mass number related?
it isn't - the number of electrons in an atom will be the same as the proton number of that atom, but the mass of an atom includes the number of neutrons, and in every stable element heavier than hydrogen, the number of neutrons is the same as or greater than the number of protons. Also, the mass will vary between isotopes of the same element, which will contain the same number of protons and hence electrons but a different number of neutrons. Generally, in stable nuclei, as the number of electrons in an atom in creases, the mass increases as well, but these are not directly linked as to be stable, heavier nuclei require a greater proportion of neutrons in the nuclei so will have a greater mass to electron number ratio
How do you get atomic mass?
Atomic mass is found by adding together the individual masses of the numbers of protons, neutrons, and electrons in the atom.--> Atomic Mass = protons + neutrons
The atomic mass of an atom is determined by the combined masses of its what?
The atomic mass of an atom is determined by the combined masses of its protons, neutrons, and electrons. While electrons contribute very little to the atomic mass, the protons and neutrons, found in the nucleus, account for the majority of an atom's mass.
Where can most of the mass in an atom be found?
Most of the mass in an atom can be found in the nucleus, which houses the protons and neutrons. Protons and neutrons are much more massive than electrons, which orbit the nucleus in the electron cloud.
What is the mass of an atom mainly determined by?
The sum of masses of protons, neutrons and electrons.
What information does the atomic mass of an elemt provide?
the number of protons and neutrons in an atom. Atomic mass is found by adding together the individual masses of the numbers of protons, neutrons, and electrons in the atom. --> Atomic Mass = protons + neutrons
How are electrons different from neutrons?
Electrons are negatively charged subatomic particles found in the electron cloud surrounding the nucleus of an atom, while neutrons are neutrally charged subatomic particles found in the nucleus of an atom. Electrons are much smaller in size and mass compared to neutrons, with electrons being approximately 1/1836th the mass of a neutron. Electrons are involved in chemical reactions and bonding, while neutrons help stabilize the nucleus of an atom.
Why atomic mass is always greater than atomic number?
Atomic mass includes the total mass of protons, neutrons, and electrons in an atom. Since protons and neutrons contribute significantly to the mass of an atom, atomic mass is generally greater than atomic number, which represents the number of protons in the nucleus. Electrons have a much smaller mass compared to protons and neutrons, so they have less impact on the overall atomic mass.
How many protons neutrons and electrons are found in phosphorous?
Phosphorus has an atomic no. of 15 and its atomic mass is 31.=we know,atomic no.=number of protons==also, atomic mass=no.of protons+no. of neutrons==this implies, 31=15+no. of neutrons= 31-15=no. of neutrons= 16=no. of neutrons==also,no. of protons=no, of electrons=so, total no. of protons=15total no. of electrons=15total no. of neutrons=16
