What neutral element has 43 neutrons, 36 protons, and 36 electrons? What element has the electron configuration Xe 4f6 6s2? Which element has the following electron configuration? 1s22s22px12py12pz1 Which elemen
also called the inert gases, did not react with anything. However, the element fluorine is so highly reactive that it actually can react with these elements. An elements reactivity is highly dependent on its natural stability created by the number of protons, neutrons, and electrons in each ato...
A line of radioactive cosmetics introduced in 1930 Each element comes in varieties called isotopes whose atoms differ in the number of neutrons in their nuclei. You’ve probably heard of uranium-235 and, well, the polonium-210 that did in former KGB officer Alexander Litvinenko. The former is...
An atom has three types of very tiny particles called protons, neutrons and electrons. The center of an atom is called the nucleus, and it is made up of protons and neutrons. The electrons in an atom fly around and above the nucleus in a cloud-like formation. The protons have a positiv...

So, for example, lead has 82 protons and between 120 and 132 neutrons in its nucleus, whereas hydrogen, the lightest element, has just one proton and occasionally one or two neutrons. The number of protons in an atom of any given element is always the same. Physicists call this the ...
element in the periodic table.But the atom is not the smallest unit of matter.Experiments found that each atom has a tiny, dense nucleus,surrounded by a cloud of even tinier electrons.The electron is, as far as we know,one of the fundamental, indivisible building blocks of the universe.It...
This hydrogen-burning helium forging phase is what astrophysicists call the main sequence lifetime of a star. But, helium isn't the only chemical element being forged in the sun. When and where do stars forge heavier elements? How does nuclear fusion forge the chemical elements?
The nuclear notation of an atom or an ion shows the number of protons, the number of neutrons, and sometimes, the number of electrons. However, these are not presented as they are because they are encoded as the mass number and the atomic number. With this, it is easier ...
What element has the most stable isotopes?Isotopes:Each element in the universe can be subcategorized into different isotopes of that element. These isotopes are defined by the number of neutrons found in the element's nucleus, which can vary from atom to atom. Isotopes can either be stable ...
