1. Why is that during alpha emission, the atomic number decreases by two, and the mass number decreases by four? In your answer yu should consider what alpha particle is?

2. In beta emission, the atom loses an electron, yet the atomic increase by one and the mass number stays the same. How is this possible? It may help if you consider what happen to the number of neutrons and protons.

3. if an element is bombarded by an neutron and subsequently emits a gamma ray, then it follows that the mass number will increase by one. How is it then, the atomic number remains unchanged?

Is Atomic Mass and Atomic Weight the same terms? Or is Atomic mass and Mass Number...

Is Atomic Mass and Atomic Weight the same terms? Or is Atomic mass and Mass Number the same terms? On the MCAT Kaplan books it says that atomic mass and mass number are the same thing but online and other chemistry textbooks, atomic mass and atomic weight are the same thing. Can someone please clarify which two terms are the same thing or are they all different? I really need help to make sure I understand this for the MCAT.

If an element has an atomic number of 7 and an atomic mass number of 15,...

If an element has an atomic number of 7 and an atomic mass number of 15, how many protons, neutrons, and electrons does it possess? a) 7 protons, 8 neutrons, and 7 electrons b) 7 protons, 8 neutrons, and 8 electrons c) 8 protons, 7 neutrons, and 8 electrons d) 15 protons, 8 neutrons, and 8 electrons

Name the element with atomic number (Z) = 15 and atomic mass number = 31, Use the symbol, not the word. How many electrons does the neutral atom of this element have? Use a number, not a word. How many neutrons does the neutral atom of this element have? Use a number, not a word.

1. A one-electron atom has atomic number ?, mass number ? and a spherical nucleus of radius ? . Assume electric charge +?? is uniformly distributed throughout the volume of the nucleus. Ignoring spin, use first order non-degenerate perturbation theory and the hydrogenic wave functions adapted to the one-electron atom to determine the dependence of the ground state energy of the atom on ?

Explain why atomic emission spectroscopy can be used for multi-elemental analysis, but atomic absorption is used mostly for quantification of single element.

Can someone explain to me the difference between atomic mass, mass number, and atomic weight. I have 4 different textbooks saying different things and I am so confused. Is atomic mass and mass number the same thing? Or is atomic mass and atomic weight the same thing? Or are all three terms different things with different meanings? Can someone please clarify in simple terms the meaning of these three terms and give an example for each, thanks so much! I...

A hypothetical element Ec has an atomic number of 156 and an atomic mass of 300....

A hypothetical element Ec has an atomic number of 156 and an atomic mass of 300. 1. How many neutrons and electrons would be found in a neutral Ec atom? 2. If one proton were removed from Ec, would it still be the same element? 3. If one electron were to be gained by an atom of Ec, would it still be the same element? Would anything change about the element?
