Could another type of atom just happen to have 11 protons, 11 electrons and 12 neutrons ? No. The number of protons = the 'Atomic Number', which is sometimes referred to as 'Z', defines the type of atom, i.e. which element it is an atom of. As indicated in the List of Chemi...
Protons and neutrons have a mass of 1.67 x 10-27 kg, and electrons have a mass of 9.11 x 10-31 kg. A uniform electric field can An object has eight million more electrons than protons. What is the net charge of the object? An object has eight million m...
An atom has 20 electrons and 20 neutrons. What is the mass of this atom? What charge would an ion that has 11 protons, 11 neutrons, and 10 electrons would have? What is the difference between protons, neutrons, and electrons? How many protons, electrons, and neutrons are in Hydrogen-3...

An atom containing 9 protons, 11 neutrons, and 8 electrons is what? a. charge neutral b. sodium atom c. ion d. cannot exist What is the charge of an ion with 12 protons and 11 electrons? Electronic configurations follow from the...
In emission of an electron, a neutron is converted into a proton. Therefore, number of neutrons decreases and the number of protons increases. The neutron to proton ratio decreases. In the emission of a positron, a proton is converted into a neutron. Hence the ratio increases. Show More ...
What Are Neutrons? Neutrons, along with protons, are subatomic particles found inside thenucleus of every atom. The only exception is hydrogen, where the nucleus contains only a single proton. Neutrons have a neutral electric charge (neither negative nor positive) and have slightly more mass than...
