How is mass related to electrons?
because the electrons plus the nuetrons equal the mass
Do electrons have mass?
Yes, electrons have a mass of 9.1094 X 10−31 kg.
When calculating an atoms approximate mass how is the mass of electrons figured?
electrons are the same as protons
An ion of iron has an 26 protons 30 neutrons and 23 electrons. What are its atomic number atomic mass and net charge?
Atomic number : 26Atomic mass : 55.845 Net charge : +3
How do you calculate the atomic mass of an element?
If you know the mass of one mole of those atoms (the mass number listed on the periodic table), then you divide that number by Avogadro's constant: 6.022x10^23 which gives you the mass of one single atom
What is the mass of an atom with 3 protons 4 neutrons and 3 electrons?
10.
What is the atomic particle that has an extremely small mass compared to the others?
Of the 3 atomic particles protons, neutrons and electrons, electrons have the smallest mass.
Why is it important for electrons to have no mass?
Actually, electrons do have mass.
What is the mass of an element with 4 protons 6 electrons 3 neutrons?
The mass of the isotope 7Be is 7,01692983(11) u. The isotope 7Be has 4 protons, 3 neutrons and 4 electrons (not 6).
What is the mass number of an atom with 3 protons electrons and 4 neutrons?
10.

An atom that has 3 protons 4 neutrons and 3 electrons has an atomic number of?
The number of protons an atom has is equal to its atomic number. In this case, there are 3 protons, so its atomic number is 3 and this is lithium (Li), the third element on the periodic table. Atomic mass is sum of the number of protons and neutrons in the nucleus. Here, that is 3 and 4, respectively, giving our atom an atomic mass of 7. The number of electrons does not affect either the atomic number or the atomic mass, but instead determines the bonding properties of the atom and whether it has a charge. If the number of electrons is equal to the number of protons, as is the case here, the charge is neutral (0). If there are more electrons than protons, the atom will be negatively charged (5 electrons and 3 protons --> charge = -2), and if there are more protons than electrons, the atom will be positively charged (2 electrons and 3 protons --> charge = +1).
How many protons will lithium have if the mass number is 8?
lithium has 3 protons which would also be 3 electrons.
An element's atomic mass does not include the mass of its?
...electrons, as they account for a negligible mass relative to the atom as a whole (electrons make up 1/1840th of the total mass, to be precise).
How many electrons does a aluminum atom lose to form an ion?
an aluminum atom will lose the 3 electrons on its outer shell 2 for an aluminum ion.
Do electrons have mass?
Yes, electrons have a mass of 9.1094 X 10−31 kg.
