What happens to the atomic number of sodium when it loses one electron?
Atomic number is the number of protons in the nucleus of an atom. Therefore, sodium's atomic number is always 11, even if it loses 1 electron. However, when a sodium atom loses 1 electron, it will form an ion with a 1+ charge.
How many electrons does Rubidium have?
The atomic number of rubidium is 37. That means it has 37 protons and 37 electrons. After we fill in the first 37 orbitals with electrons, we get the configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s1. Since 5 is the highest numbered shell, rubidium has 1 valence electron.
What is the charge of an ion that contains 21 protons and 19 electrons?
This ion will have a charge of -1. The atomic number is the number of protons in the atom's nucleus. A neutral atom will have a number of electrons equal to the atomic number, which is the number of protons in that nucleus. Since you have an extra electron your atom has a negative charge of one electron's worth, or minus one, which is 1.6 x 10-19 coulombs.
What is the number of neutrons for rubidium-87?
forgive me if i do not remember exactly but i believe a Rubidium atom contains 19 electrons 20 neutrons and 19 protons
What Potassium has an atomic number of 19 if often forms an ion by losing 1 electron What charge would the ion have?
+1
What is different about francium and rubidium?
Francium is radioactive and rubidium not. Also the electron configuration, atomic number, physical properties, hazards etc. are different.
What is rubidiums atomic mass?
Rubidium is a metal element. Atomic mass of it is 85.46.
What is orbital notation for rubidium?
Rubidium has an atomic number of 37, making it an alkali metal. This means that its last shell is an s with only one electron. The full notation is [Kr] 5s1.
How do you calculate the number of proton neutron and electron using atomic no and mass no?
atomic # = protons atomic mass - atomic number = neutrons atomic # - charge = electrons
What is the Noble gas notation of rubidium?
