What number of neutrons would equal a mass of one gram with the mass of a neutron of 1.67 times 10 to the negative 24 power?
1g neutrons/(1.67x10-24g/neutron)=5.99x1023 neutrons.
If beryllium has an atomic number of 4 and an atomic mass of approximately how many neutrons does beryllium atom have?
Since the mass number is protons plus neutrons, it would have 5 neutrons.
When you subtract the atomic number from the atomic mass of any element you get what?
Atomic mass= Atomic no. + no. of neutrons So when the atomic no. is subtracted from the atomic mass, the result would be equal to the number of neutrons present in the nucleus of the atom of the element.
How would you calculate the atomic mass of atom without using the periodic table if you know the number of protons electrons and neutrons?
Add the number of protons plus the number of neutrons for an approximate answer. Compared to protons and neutrons, electrons have zero mass - it takes over 1800 electrons to equal the mass of a proton or neutron.
To find the number of neutrons in an atom you would subtract what?
You would subtract the atomic number from the mass number.
An atom with an atomic number of 9 and mass number of what is the atomic mass?
This is an Oxygen-17 isotope.Isotopic mass = 16.9991315 u. (Approximately equal to no. of protons + no. of neutrons = 8 +9 = 17)Similar Questions:What type of atom or ion would have 8 protons 9 neutrons and 10 electrons?
Why are protons and neutrons always equal in number?
Because they are both in the nucleus and if they weren't the element would be radioactive.
What number of neutrons would equal a mass of one gram with the mass of a neutron of 1.67 times 10 to the negative 24 power?
1g neutrons/(1.67x10-24g/neutron)=5.99x1023 neutrons.
If beryllium has an atomic number of 4 and an atomic mass of approximately how many neutrons does beryllium atom have?
Since the mass number is protons plus neutrons, it would have 5 neutrons.
How do you find the number of neutrons protons and electrons in an atom if the atom is neutral?
The number of electrons in an atom is always equal to the number of protons in that same atom. Since the atomic mass of a periodic element equals the weight of the atoms protons AND its neutrons, the following equation can be used to calculate the number of any given particle in an atom: number of neutrons = atomic mass - atomic number
True or false The number of neutrons is equal to the atomic number?
This would be false. The atomic number is equal to the number of protons and the neutrons are the number you add to protons to equal the mass number (to find round the atomic weight).
How do you find the number of neutrons from the mass number?
Atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom the number of neutrons would equal the mass number minus the atomic number.
How many proton's neutrons and electrons of Pb are present with a mass number of 207 and an atomic number of 82?
atomic mass equal to number of protons and neutrons. If Pb has a mass of 207 and an atomic number of 82, that means that there are 82 protons in Pb, which also means there should be 82 electrons. That leaves neutrons, which would be 207-82=125 neutrons.
Protons plus neutrons plus electrons equals mass number?
The atomic weight/mass is the average weight of all the isotopes of that element. Adding the number of protons and neutrons together does equal to the atomic weight, but only if you round the decimal.For example the element sulfur (atomic number 16) has an atomic mass of 32.066. This is not a whole number, but that does not mean that sulfur has 16.066 neutrons. Instead, you would just say that the atomic mass is 32 amu and subtract the number of protons, which is the same as the atomic number, from the atomic mass. Sulfur therefore has 16 neutrons, protons, and electrons.
When you subtract the atomic number from the atomic mass of any element you get what?
Atomic mass= Atomic no. + no. of neutrons So when the atomic no. is subtracted from the atomic mass, the result would be equal to the number of neutrons present in the nucleus of the atom of the element.
If someone picks up an excess of electrons while walking across a carpet their charge would be?
negative protons are positively charged neutrons are neutral electrons are negative the masses of neutrons and protons are approximately equal and electrons, which "orbit" around the nucleus (the protons and neutrons) are much smaller mass-wise protons and electrons charges are equal and opposite
What is the atomic number for a particular atom of carbon that has 6 protons 6 electrons and 8 neutrons?
the atomic number would be 6. the atomic number is always equal to the number of protons.
