the elements on the left side are most reactive. reactivity decreases as you move to the right. the noble gases (last group) are least reactive.
The metals on the left side of the periodic table are considered to be highly reactive to air while in room temperature. The ones on the right side are less reactive and are often used for construction.
Electronegativity increases across (left to right) the periodic table and decreases on going down.
False,reactivity of elements generally decreases from left to right.As free electrons become less,reactivity decreases.So the given statement is false.
The rows across the periodic table are called periods.
Yes
Chemical reactivity first decreases.then it increases as we move across a period.
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
No, right to left.
Maybe there is no pattern...no it fals
Reactivity of metals decreases from left to right in the specific period of theperiodic table.
Reactivity of metals decreases from left to right in the specific period of theperiodic table.
Reactivity of metals decreases from left to right in the specific period of theperiodic table.
Reactivity of metals decreases from left to right in the specific period of theperiodic table.
Decrease reactivity
Reactivity increases the farther down you go in the Periodic Table.
Atomic radius usually decreases from left to right across a period of the periodic table.
Some good questions about periodic table: where are metalloids placed? why group 18 elements are inactive? How many groups and periods are in periodic table? How reactivity changes across and down the group?
