Reactivity generally increases as you move from right to left across a period and from top to bottom down a group on the Periodic Table. This is because elements on the left side of the table have fewer electrons in their outer shell, making them more likely to lose electrons and react with other elements.
Yes, reactivity generally increases as you move down a group in the periodic table due to the increase in the number of electron shells, which leads to a greater distance between the outer electrons and the nucleus, making it easier for the outer electrons to be involved in chemical reactions.
Reactivity generally decreases as you move from left to right across the periodic table within a period. Atoms on the left have fewer valence electrons and are more reactive in forming bonds compared to atoms on the right, which have more valence electrons and are less inclined to form bonds. However, reactivity tends to increase as you move down a group within the periodic table.
True. Generally, the reactivity of metal elements increases as you move from left to right across the periodic table. This is because as you move towards the right, the elements have fewer electrons in their outer shell, making them more likely to lose electrons and react with other elements.
The reactivity of nonmetals generally decreases as you move from left to right across the periodic table. This is because nonmetals on the right side of the periodic table have a higher electronegativity, making them less likely to lose electrons and more likely to gain electrons.
Groups in the periodic table are vertical columns that contain elements with similar chemical properties. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical behavior. There are 18 groups in the periodic table.
Maybe there is no pattern...no it fals
Decrease reactivity
Yes, reactivity generally increases as you move down a group in the periodic table due to the increase in the number of electron shells, which leads to a greater distance between the outer electrons and the nucleus, making it easier for the outer electrons to be involved in chemical reactions.
Periodic Table - Or Table of Reactivty
If the question means REACTIVITY.. well..no, it decreases across and increses downwards..
False. The most chemically reactive metals are in the two leftmost columns.
No it decreases.
The reactivity increases with increasing numbers of electron shells (energy levels).
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
a Periodic Table organises the different elements, according to the atoms' mass, type, properties, reactivity etc. See the question about: periodic table patterns
Chemical reactivity first decreases.then it increases as we move across a period.
Reactivity is associated with position. Chemical properties of element can be determined from its position.
