WebNon-metals Period - reactivity increases as you go from the left to the right across a period. Group - reactivity decreases as you go down the group. Why? The farther right and up you go on the periodic table, the higher the electronegativity, resulting in a more vigorous exchange of electron. Read also: This is the background info you need to ... WebOct 9, 2024 · Period – reactivity decreases as you go from left to right across a period. The farther to the left and down the periodic chart you go, the easier it is for electrons to be given or taken away, resulting in higher reactivity. Group – reactivity decreases as you go down the group. How does metallic character change when we move across a period?

WebIt 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. Both melting points and electrical conductivity vary across the period. WebThe most reactive metals have the greatest tendency to lose electrons to form positively charged ions. Metals, therefore, become more reactive as they are located further to the … WebSep 14, 2024 · Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character. Periodic trends, arising from the arrangement of the periodic table, provide chemists with an invaluable tool to quickly predict an element's properties. impostare wds
