If it has 7 protons, that’s nitrogen. But the logic of the periodic table also relies upon the number and organisation of electrons in an atom. Let’s take chlorine as an example. It is ...

Students look more deeply into the structure of the atom and play a game to better understand the relationship between protons, neutrons, electrons, and energy levels in atoms and their location in ...

Players read questions about energy levels and score points by picking the correct element as the answer. Electrons are in regions around the nucleus that are different distances away from the nucleus ...

Bismuth is in Group 15 of the periodic table. The s, d and f orbitals are all full, but the p orbitals contain three out of a possible six electrons. So bismuth has partially filled orbitals and ...

Atoms of non-metal elements gain electrons in some of their reactions ... See the study guide on groups in the periodic table for more information.

Electronegativity, an essential characteristic of all elements in the periodic table, measures an atom's ability to attract electrons towards itself within a chemical bond. This vital theoretical ...

As you move from left to right across the periodic table, atoms have more electrons in their outer energy level and more protons in their nucleus. The greater attraction between the increased ...

which are important for an element's placement in the periodic table. "Due to the presence of huge electrostatic forces, electrons in superheavy atoms move with velocities close to light speed ...

Some elements in the periodic table, such as carbon, silicon, and germanium, are intrinsic semiconductors due to the number of electrons in their outermost electron shells. By comparison ...
