Where are neutrons located? What makes up the nucleus of an atom? How many quarks are there in a helium-4 nucleus? Does the number of neutrons change in alpha decay? How does a cyclotron produce protons? How do radioactive isotopes differ from isotopes?
The atomic number of any element refers to the number of protons that element contains. This number is added to the number of neutrons to create what's known as the element's mass number. Answer and Explanation:1 The atomic number for boron is five. This means that boron contains five pr...
Not all the atoms of an element need have the same number of neutrons in their nuclei. In fact, it is precisely the variation in the number of neutrons in the nuclei of atoms that gives rise to isotopes. Hydrogen is a case in point. It has the atomic number 1. Three nuclei with one...
Mass number, in nuclear physics, the sum of the numbers of protons and neutrons present in the nucleus of an atom. The mass number is commonly cited in distinguishing among the isotopes of an element, all of which have the same atomic number (number of p
Atomic number Z represents the number of protons per atom. Mass number Z + N is equal to the number of protons Z plus the number of neutrons N present in the nuclei. Mass numbers of the most abundant isotopes are given in order of decreasing abundance. For example, Cadmium Cd-48 mass ...
The concluding segment displayed the highest concentrations of metals, including lead (445-17333 ppm), manganese (6845-146927 ppm), copper (764-13426 ppm), zinc (2874-24479 ppm), cadmium (011-223 ppm), iron (05-49%), and aluminum (07-32%). Employing background crustal values and ...
The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element. The number of protons determines the element, but the number of neutrons in the atom of any one element can vary. Each variation is an isotope. Aluminum has six radioactive isotopes....
Isotopes are two or more forms of an element. Isotopes differ from each other according to their mass number. The number written to the right of the element's name is the mass number. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element...
uranium 235- a uranium isotope with mass number 235; capable of sustaining chain reactions uranium 238- the commonest isotope of uranium; it is not fissionable but when irradiated with neutrons it produces fissionable plutonium 239 pitchblende,uraninite- a mineral consisting of uranium oxide and ...
The atomic number of an atom of an element is 17 while its mass number is 35. How many neutrons does the atom have? How do you find the atomic mass of an element? Identify the isotope that has an atomic number of 76 and a mass number of 192. ...
