Atoms with the same number of protons but different numbers of neutrons are called isotopes. Mass of isotopes Isotopes containing more neutrons have a greater mass. 具有相同质子数不同中子数的原子互为同位素。中子数多的同位素质量更大。 In spite of these differences, isotopes of an atom have the ...
C)each peak corresponds with an isotope and there are four isotopes D)the spectrum shows several different atoms Step 1:Identify the element represented in the mass spectrum. We are asked about the mass spectrum for iron. Step 2:If given, identify all mass peaks from the m...
• The different manifestations of the same atom that vary only in neutron number are called isotopes. The proton-plus-neutron number of a given isotope is given using a left superscript next to the element symbol. This atom could therefore be represented by 18 proton balls (pink) and 22 ...
youcantalk about the half-life of an atom. If you take a radioactive atom and wait for it to decay, the half-life is how long you’d have to wait for there to be a 50% chance that it will have decayed. Very radioactive ...
the neutral, non-charged state, every atom has the same number ofelectronsas it does protons. Elements starting with helium also contain a number ofneutronssimilar to and usually slightly in excess of the proton number. Variants of elements with different numbers of neutrons are called isotopes....
combine to form a single heavier atom. At extremely high temperatures, the nuclei of hydrogen isotopes deuterium and tritium can readily fuse, releasing enormous amounts of energy in the process. Weapons that take advantage of this process are known asfusion bombs,thermonuclearbombsorhydrogen bombs....
The number of protons for an element is fixed and represented by its atomic number. The number of neutrons can vary, which is the basis for isotopes of an element. Neutrons and protons have comparable mass, with their quantities being the basis for the atom's mass number. The elect...
the neutron and proton that are found inside the nucleus of the atom. The SI unit of the mass of the atoms is a kilogram, but it is usually represented in a.m.u(atomic mass unit). We can say the atomic mass is nothing but the weightage average of all the isotopes of the element....
The natural sources of all the elements. Artificial elements are created atom by atom, and almost everything else is made in supernovas and neutron star collisions. Artificial isotopes can be created by bombarding existing isotopes with “slow” neutrons, some of which stick to ...
The intersection set C of two given sets A and B is the set that have the elements which are common in the both sets A and B. It can be represented by the following symbol: C=A∩BAnswer and Explanation: The given sets: U={1,2,3,4,5,6,7} and A=...
