Reactivity of elements periodic trend
WebPeriod 3 is the third row in the periodic table. It contains the elements sodium, magnesium, aluminium, silicon, phosphorus, sulphur, chlorine, and argon. Period 3 shows trends in atomic properties: Ionic radius decreases across the period. First ionisation energy increases across the period. WebThe reactivity of Group 1 elements increases as you go down the group because: the atoms get larger the outer electron gets further from the nucleus the attraction between the nucleus and outer...

WebExplain they will be looking at trends on the periodic table, one of which is the reactivity of elements. Discuss reactivity. A chemical that reacts easily with other substances is considered to be highly reactive. Explain that the most reactive elements are found in group 1 and they become more reactive as you go down the list. WebJul 15, 2024 · 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.
WebPeriodic trends are repeating patterns found in the periodic table as you move across a period or down a group. In the periodic table, rows are known as periods and columns are known as groups. Elements in the same period have the same number of electron shells, but differ in their number of outer shell electrons. WebThe greater attraction between the increased number of protons (increased nuclear charge) and electrons, pulls the electrons closer together, hence the smaller size. As you …

WebJan 23, 2024 · Reactivity of Elements. Reactivity of an element is determined by its electropositive nature. Increased metallic character leads to more electro-positivity that in turn, leads to more reactivity. In the Modern Periodic table, while moving across left to right, with the decrease in the metallic nature of an element, its reactivity also goes down.
WebThe elements within the same group of the periodic table tend to exhibit similar physical and chemical properties.
