Because while a positively or negatively charged beam contains either protons or electrons, neutrons have no charge whatsoever and does no harm to the living tissue.
Protons have a positive charge. Therefore protons can cause ionization in living cells.
In any atom,there are protons, neutrons and electrons. As the name would suggest, neutrons carry no charge. Protons carry a positive charge and electrons carry a negative charge. So in an atom that has no charge there has to be an equal number of protons and electrons.
Neutrons and protons are found in the nucleus of an atom. Neutons as their name suggest are neutrally charged while protons carry positive charge. Thus the number of protons gives the nucleus its positive charge.
No, although some theories suggest that there is a tendency of protons and neutrons in massive nuclei to temporarily group into alpha particle like clusters. Such clustering predicts differences in stability between different isotopes.
93 protons and 93 electrons; the number of neutrons is different for each isotope. For ex.: 144 neutrons in neptunium 237 Tthe number of neutrons is the difference between the atomic mass of an isotope and the atomic number. the sky is pnk
As the name suggest, ozone can be found in the ozone layer. This ozone layer protects us from the harmful radiations of the sun.

If it has 11 electrons it must have 11 protons to balance the charge. So the element is Na. But you know it's going to be an isotope of Na since the number of protons and number of neutrons are different. To find out which isotope you have, you must get the mass number which is just the number of protons plus the number of neutrons (remember, they are the only ones that have mass) 11+12= 23 So you have Na-23
No, however more radical points of view would suggest otherwise. As far as the danger factor is concerned (not as in "harmful" like greenhouse-gases harmful, as the question may suggest), cows are more likely to injure or kill a human being than a shark. According to most studies, 10 times fatalities occur with cows per year than with sharks.
Nobody did. Neutrons have always existed. Earnest Rutherford suggest neutrons might exist about 11 years before their existence was proven.
Some scientific theories suggest that over EXTREMELY long time periods, protons themselves can decay. If so, then a few trillion years from now, the universe may eventually decay into a sea of free neutrons.
It could be quite harmful but it depends on how much chalk they ate. I suggest taking them to the doctor just to check that everything is ok.
Unfortunately, wearing Denim pants IS harmful to your health... I suggest you avoid them
Yes. You get lots. They are very harmful, so I suggest you don't.
