An atom of an element weights 3.00 x 10^-23 g. What is the atomic mass of this element? An atom has a mass of 19.00 amu (atomic mass units). Determine the mass of the atom in: \\ A. grams B. kilograms Which two subatomic particles have approximately the sa...
To determine which of the given sets of elements are Dobereiner's triads, we need to apply the concept of Dobereiner's triads. A triad consists of three elements where the atomic mass of the middle element is approximately the average of the atomic ma
In the case of atoms, it has protons, neutrons, and electrons in it, and each of these sub-atomic particles carries a definite mass, although a neutron is chargeless it has a mass. Answer and Explanation: Atomic mass The...

Has a mass about the same as that of a proton 4. Is att The nucleus of an atom consists of which particles? Name three subatomic particles found in the atom of an element. If an atom has 17 electrons, 20 neutrons, and 19 protons, what is its approximate ...
Sulfur: Sulfur is a chemical element with the atomic number 16. It is part of many important biological molecules because it is part of the amino acids cysteine and methionine which are in many proteins. Oxidation number The oxidation number is very important for naming compounds. ...
Bismuth is the most naturally diamagnetic element and has one of the lowest values of thermal conductivity among metals. Bismuth was long considered the element with the highest atomic mass that is stable, but in 2003 it was discovered to be extremely weakly radioactive: its only primordial ...
In 2004, scientists at the Cyclotron produced and observed a new isotope of the element germanium, called Ge-60 In that same year, Michigan State University, in consortium with the University of North Carolina at Chapel Hill and the government of Brazil, broke ground on the 4.1-meter Southern...
(D). 18 ml of water. Hence, from all the values, we can see that the number of molecules of water is maximum $6.022 \times {10^{23}}$ in 18ml of water. So,
a) Atomic mass b) Chemical stability c) Number of neutrons d) Number of protons What is the element that has an isotope which has an atomic weight of 56 and 29 neutrons? What is the energy released when 0.5 grams of uranium 235 under goes a fission reaction? Isotopes of an ...
