Example: How to find the atomic mass of an oxygen molecule with 9 neutrons. Solution:

The atomic number or proton number is defined as the total number of protons in the nucleus and is given the symbol Z. The number of electrons in an electrically-neutral atom is the same as the atomic number. The total electrical charge of the nucleus is therefore +Ze. Source: chemwiki.ucdavis.edu. The atom consists of a small but massive ...

A double ionised lithium atom is hydrogen like with atomic number `3` (i)Find the wavelength of the radiation to excite the electron in `Li^(++)`from the first to the third bohr orbit (lonisation energy of the hydrogen atom equals `13. 6eV`

Hydrogen peroxide is a colorless, viscous and unstable liquid, which is used in disinfectants and bleaches. It has no atomic number since it is a compound.

Example Exercise 9.1 Atomic Mass and Avogadro's Number. The atomic mass of each element is listed below the symbol of the element in the periodic table: Cu 63.55 amu, Hg 200.59 amu, S 32.07 amu, and He 4.00 amu. The mass of Avogadro's number of atoms is the atomic mass expressed in grams. Therefore, 6.02 . ×. 10. 23. atoms of

Q.17 A hydrogen like atom (atomic number Z) is in higher excited state of quantum number n. This excited atom can make a transition to the first excited state by successively emitting two photons of energy 22.95eV and 5.15eV respectively. Alternatively, the atom from the same excited state can make transition to the second excited state by successively emitting two photons of energies 2.4eV ...

A hydrogen-like atom is an atom consisting of a nucleus and just one electron; the nucleus can be bigger than just a single proton, though. H atoms, He + ions, Li 2+ ions etc. are hydrogen-like atoms in this context. We'll see later how we can use the exact solution for the hydrogen-like atom as an approximation for multi-electron atoms.

The atomic weight (also known as relative atomic mass) is a quantity used to express the average weight of an atom. Atoms consist of electrons, protons, and neutrons. Protons and neutrons are mainly responsible for the mass of an atom. For a given element, the proton number (more commonly known as the atomic number) is fixed, but the neutron ...
