How many protons does argon have? How many valence electrons does protactinium have? How many valence electrons does darmstadtium have? How many valence electrons does hassium have? How many valence electrons does einsteinium have? How many valence shell electrons does an atom of indium have?
A new substance has been found with 73 protons and an atomic mass of 192. How many neutrons does it have? How many copper atoms are in a pure copper statue with a mass of 144 kg? You are given a small piece of gold colored material and want to determine if it is actually gold. ...
How many neutrons and nominal mass for {eq}\displaystyle \rm ^{1}H_2^+ {/eq}? Atomic Mass: The atomic mass of an atom or molecule can be determined based on the "number of protons and neutrons". "The total atomic mass or molecular mass of the atom or a molecule is the sum or...
To comprehend how we can gain access to such precise numbers, we have to ask ourselves: how does a breathalyzer work? What do those figures mean? And how do police officers find out if someone they suspect has been drinking is actually legally drunk? Many officers in the field rely ...
How many chloride ions are present in a 12.4-gram sample of calcium chloride? Ions: Ions are charged substances that posses more electrons than protons. We can form ions from the loss or gain of electrons in an oxidation reduction reaction. Ionic compounds can be formed from thei...
We thank would like to thank the many researchers who have contributed over many years to the ideas in this paper. Conflicts of Interest The funders had no role in the design of the study; in the collection, analyses, or interpretation of data; in the writing of the manuscript; or in th...

(Atoms have protons and neutrons in their nucleus, and surrounding that, they have their electrons arranged in orbitals., Orbitals describe the location of an electron as well as its wave-like behavior.)That means all of the elements in the third period — sodium, magnesium, aluminum, silicon...
Magnesium is atomic number 12. That means it has 12 electrons and 12 protons. Now, how are the elections configured, and how many electrons are in the valence shell? The first two shells are full, the first with two electrons and the second with eight. All that is left are two electron...
To maintain workable diffusion distances, an organism must have many small cells instead of one large cell. So, an alien would be multi-celled if it is larger than a microbe. (We would not expect to find a light-years wide, single-celled organism like that portrayed in the original Star...
