If you know the atomic number and the mass number of an isotope of an element, how can you determine the number of protons and neutrons? Electrons orbit around the atom's nucleus just like planets orbit the sun. True or false? What is the avera...
atomic mass is the average mass of the protons, neutrons, and electrons in an atom. its unit is a unified atomic mass and is denoted by the symbol ‘u’. q2 what is one amu? an atomic mass unit or one amu is the mass unit equivalent to the one-twelfth mass of one atom of the ...
First, they choose an atom of carbon-12 to be the standard atom. They fix its masses as exactly 12 units. Look at the carbon atom. How many protons, neutrons and electrons in it?(Write down the title on the blackboard) S: It has 6 protons, 6neutrons and 6 electrons. T: Right. ...
Which isotope of lithium has 3 neutrons? What is the most common isotope? A certain isotope X^+ contains 54 electrons and 78 neutrons. What is the mass number of this isotope? What isotope has 8 protons, 8 neutrons, and 8 electrons?

symbols tell us: The element (ex. uranium) top number is the mass number # protons + # neutrons bottom number is the atomic number # protons You can determine the number of neutrons by subtraction mass number → atomic number → 238 (mass #) - 92 (atomic #) = 146 (# of neutrons)...
Thus the atomic mass of oxygen is expressed as the weighed average of the atomic masses of these three isotopes. Atomic mass of oxygen=[(99.763*15.995)+(0.037*16.999)+(0.2*17.999)]/100 = 15 u
We consider a possible mechanism of emergence of particle masses due to electromagnetic interaction. The proposed theory is relativistic but non-quantum. In this regard, we consider only three types of particles (electrons, protons, and neutrons), and the difference of particle masses is explained ...
