What is the mass number of sodium if the numbers are 11 and 12?
The proton number of Sodium is 11. The mass number is just under 23 (22.989...). This is because of the different isotopes of sodium and there scarcity.
What the mass of a proton of a mole of sodium?
Mass of one proton = 1.67 X 10 -27 kgA mole of sodium atoms = 6.022 X 1023 atoms11 protons per sodium atom11 * 6.022 X 1023= 6.62 X 1024 protons per mole sodium==================================so,6.62 X 1024 * 1.67 X 10 -27 kg= 0.011 kilograms of protons in mole sodium====================================( 11 grams of protons)
What is the mass number for sodium?
the mass number of sodium is 23
How do you determine the number of neutrons for a sodium atom?
Subtract the proton number or atomic number (11) from the nucleon number or the atomic mass (23) and you get the number of neutrons = '''12'''.
How do you calculate avogadro's number?
1 / mass of a proton = avogadro's number 1 / mass of a proton = avogadro's number
What is the mass number of a neutron and a proton in hydrogen?
The mass number of a neutron is 1, as it contains one unit of mass. The mass number of a proton is also 1, as it contains one unit of mass. In hydrogen, the nucleus usually consists of one proton, so the mass number of a proton in hydrogen is 1.
What is the formula for the atomic number?
atomic number = number of proton in an element number of proton = number of electron mass number = number of proton + number of neutron therefore... atomic number = mass number - number of neutrons
What is The neutron-to-proton ratio for the isotope sodium?
That depends on which isotope of sodium you are talking about. Sodium always has 11 protons. The atomic mass of sodium is about 23, meaning there are, on average, 12 neutrons, so the average neutron to proton ratio for sodium is 12:11.
What type of particle has an atomic number of 1 and a mass number of 1?
Of the common sub-atomic particles, both the proton and the neutron have mass numbers of 1.
What is the mass number for 1 proton and 0 neutrons?
The mass number is (by definition) the total sum of proton and neutron number in the nucleus of one particular isotope of an element.
What is the atomic mass number of sodium?
Sodium is a meta element. Atomic mass of it is 23.
The charge and mass number of a proton are?
No, there are the same number of protons and electrons in an atom, but I don't think that they have the same mass. You're right, an electron is 1,836 times lighter than a proton.
