If an atom contains 14 protons, it is an atom of which element? What is the atomic number of an atom that has 6 protons, 6 neutrons, and 6 electrons? Which atom has the smallest number of neutrons? What is an atom that has a different number of neutrons than other atoms of the ...
these elements have a neutral charge. An atom becomes charged when the number of protons does not equal the number of electrons. For example, if an element has six protons but only five electrons, the net charge of the element is +1. Conversely, if an element has six protons but seven ...

However, for example, silver can form an ion with +1 charge, whereas zinc and cadmium can gain a +2 charge. To find out whether an atom in these groups form ions more generally and determine their charges, the best thing to do is directly look up the element you're interested in. ...
For example, plutonium, which is one of the heaviest elements, weighs more than 200 times as much as the lightest element of hydrogen. The diameter of a plutonium atom is only approximately three times the diameter of a hydrogen atom. ...
