No, right to left.
Down a group, the atomic number generally increases, size increases, ionization energy decreases, reactivity increases.
False,reactivity of elements generally decreases from left to right.As free electrons become less,reactivity decreases.So the given statement is false.
Reactivity increases the farther down you go in the Periodic Table.
Reactivity of non-metals increases as you move from left to right on the periodic table, or as group number increases. The most reactive non-metals are found in group 17.
Reactivity in group 1 of elements increases as we go down the group (to francium) because in the alkali metals as we go down the group number of atomic shells increases so the elements with most shells will easily release their electrons in the outer most shell.
the reactivity of metals increases as you go down a group in the periodic table. also elements in the same group have similar chemical properties because they have the same electronic configuration,i.e.they have the same arrangement of electrons
No it decreases.
The reactivity increases with increasing numbers of electron shells (energy levels).
The atomic number increases. The atomic number identifies a particular element and the elements are arranged in increasing order on the periodic table. Also, the atomic weight generally increases as well.
Chemical reactivity first decreases.then it increases as we move across a period.
Yes
Reactivity is associated with position. Chemical properties of element can be determined from its position.
