1 (a) The diagram below shows the atomic structure of an atom of an unknown element D.nucleus electron shells(i) Complete the table below.particle relative charge relative mass-11/1840 or negligible O01G+11[4](ii) Element D has another isotope. Both of them have the same chemical proper...
Atomic structure is the structure of an atom, theoretically consisting of a positively charged nucleus surrounded and neutralized by negatively charged electrons revolving in orbits at varying distances from the nucleus. Orbit is a well defined circular path around the nucleus in which an electron re...

This paper presents an algorithm for precisely and efficiently computing the Connolly surface of a protein using a proposed geometric construct called 尾-shape based on the Voronoi diagram of atoms in the protein. Given the Voronoi diagram of atoms based on the Euclidean distance from the atom ...
For pupils studying chemistry or physics, Bohr diagram worksheets can help them visualize and understand the structure of atoms. Learners can practice drawing accurate Bohr diagrams, which show the arrangement of electrons in an atom's energy levels, by
