What's the hype about?
A trend can start when one element follows the similarity of another element. Kind of like when you see someone doing something you like you wanna do the same thing and then others will follow which will create a trend.
There are three main trends the periodic table follows which are Ionization Energy, Electronegativity/Electron affinity, and Atomic radius.
Ionization Energy:
The minimum amount of energy to remove the most loosely bound electron of an isolated atom or molecule.
Electronegativity/Electron Affinity:
The ability of an atom in a molecule to attract shared electrons to itself.
The change in energy of a neutral atom when an electron is added to the atom to form a negative ion.
The trend in electronegativity does include noble gases because noble gases do not bond since they already have their desired number of valence electrons.
Atomic Radius
Describes the size of the atom,(atom) which does not have an outer barrier making this difficult to measure.
Atomic Radius is defined as half of the distance between the nuclei in a molecule consisting of identical atoms
The Three Main Trends
Analyzing each trend
Ionization energy
Increases from left to right and decreases from top to bottom. It increases from left to right because the nuclear charge increases from left to right and this creates a stronger force pulling toward the nucleus.
Electronegativity/ electron affinity
Increases as you go from left to right in the periodic tables and decreases as you go from top to bottom on the periodic table.
Atomic Radius:
Increases as you go down a group on the periodic table, this is because energy levels are being added. They decrease as you go from left to right across the periodic table because the increasing nuclear charge pulls the electrons closer to the nucleus.
Examples of Each Trend
1. Ionization: Celsium (Cs) {3,8939}, Francium (Fr) {4,0727}, Rubidium (Rb) {4,1771}, & Potassium (K) {4,3407}
2. Electronegativity: Silicion (Si) {1.90}, Phosphorus (P) {2.19}, Sulfur (S) {2.58}, & Chlorine (Cl) {3.16}
3. Atomic Radius: Sodium (Na) {0,191}, Magnesium (Mg) {0.160}, Aluminum (Al) {0.130}, & Silicon (Si) {0.118}
