Web22 dec. 2024 · Let's compare sodium, which is the first element in period 3, with argon, the last element in period 3. You could see here that both sodium and argon have a total of three occupied electron shells, following the pattern of elements in the same period. However, sodium has 11 protons (represented by its atomic number of 11), and argon … Web14 sep. 2024 · The Atomic and Ionic Radii. The atomic radii of period 3 elements decrease across the period since for the same number of energy levels the number of protons in the nucleus increases across the period; this leads to the increase in nuclear charge while the shielding effect remains the same hence decrease in atomic radius across the period.

Moving across Period 3, the number of protons in the nucleus increases – for example sodium has 11 protons, and chlorine has 17 protons. Web2. Define period trends. Answer: Periodic trends are specific patterns in the properties of chemical elements that are revealed in the periodic table of elements. Major periodic trends include electronegativity, ionization energy, electron affinity, atomic radii, ionic radius, metallic character, and chemical reactivity. Explanation:

WebThe atomic radius is determined entirely by the electrons: The size of the atomic nucleus is measured in femtometres, 100,000 times smaller than the cloud of electrons. In the latter case, which is the approach adopted here, it should also include ionic radius, as the distinction between covalent and ionic bonding is itself somewhat arbitrary.
