Decrease in the first part, then increase again coming more right sided: F (at right side) more reactive than O, O more than N.

Is the reactivity of the metal elements generally increase as you move from left to right across the periodic table true or false?
False,reactivity of elements generally decreases from left to right.As free electrons become less,reactivity decreases.So the given statement is false.
How does reactivity change as you move across the periodic table?
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.
A row of elements across the periodic table is an?
The rows across the periodic table are called periods.
How does the the reactivity of metals change when moving from left to right on the periodic table?
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.
O The periodic table of elements is the arrangement of elements according to?
The periodic table of elements is the arrangement of elements according to atomic number increasing from left to right across rows of the table.
Is the reactivity of the metal elements generally increases as you moves from left to right across the periodic table?
No, right to left.
How do elements changes as you across the periodic table?
the number of protons increases
Is the reactivity of the metal elements generally increase as you move from left to right across the periodic table true or false?
False,reactivity of elements generally decreases from left to right.As free electrons become less,reactivity decreases.So the given statement is false.
What are some good questions about 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?
How does chemical reactivity change as you move across the periodic table?
Chemical reactivity first decreases.then it increases as we move across a period.
What groups of metals is the most active?
The first cloumn in the periodic table has the most reactive elements. The elements decrease in reactivity as you go across the table. in other words alkali metals
What happens to the reactivity of left to right across the periodic table?
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
What happens to the reactivity of elements in groups as the atomic numbers increase across a period?
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
What happens to reactivity of elements in groups labeled a as atomic numbers increase across a period?
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
How does reactivity change as you move across the periodic table?
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.
How have scientists used the periodic table in making new discoveries?
To decide the reactivity and the propensity for particular interactions (and types of interactions) between elements.
What happens to the reactivity of elements in a group labeled A as atomic numbers increase across period?
they become more reactive since you are moving from left to right on the periodic table, the elements in group 17 are the most reactive.
