How does reactivity change as you move down a group on the periodic table?

As we go down the group, the atom gets bigger. The bigger the atom, the further away the last electron. Therefore, the attraction between the nucleus and the last electron gets weaker. This makes it easier for the atom to give up the electron which increases its reactivity.

How does metal reactivity vary down a group and across a period on the periodic table and how does that compare with trends in nonmetal reactivity?

Metal reactivity decreases from left to right across periods and increases down groups. nonmetallic characteristics increases from left to right and decreases down groups. Nonmetal reactivity increases from left to right and decreases down groups.

What happens across the period and down the group?

In general, atomic radius decreases across a period and increases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant. Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital.

Why does reactivity decrease down a group?

The reactivity of Group 7 elements decreases down the group. Non-metal atoms gain electrons when they react with metals. The electrons in the outer shell move further away from the nucleus as we go down the group and the attraction force between the electrons and the nucleus become weaker and weaker.

How does the reactivity change across a period?

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.

Does reactivity increase down a Group 2?

The reactivity increases down the group from Mg to Ba. This is because the further away an electron is from the nucleus, the weaker its attraction and the more likely it is to react with another atom.

How do periods affect reactivity?

Period – reactivity decreases as you go from left to right. Period – reactivity increases as you go from the left to the right.

How atomic radius vary in a period and in a group?

In general, the atomic radius decreases as we move from left to right in a period with an increase in the nuclear charge of the element. The atomic radius increases when we go down a group because of the addition of an extra shell.

Why does reactivity increase in group 1 and decrease in group 17?

Reactivity of Elements (decreases down the group) This is due to the fact that atomic radius increases in size with an increase of electronic energy levels. This lessens the attraction for valence electrons of other atoms, decreasing reactivity.

Does reactivity increase or decrease down a group?

Chemical reactivity of the elements 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.

Does reactivity increase down the group 1?

The reactivity of group 1 elements increases as you go down the group because: the atoms become larger. the outer electron becomes further from the nucleus.

How does reactivity change with the direction of the periodic table?

In Metals: Period – reactivity decreases as you go from left to right. Period – reactivity increases as you go from the left to the right. Group – reactivity decreases as you go down the group.

What is the trend in reactivity on the period table?

What is the trend in reactivity on the period table? Period – reactivity decreases as you go from left to right. Period – reactivity increases as you go from the left to the right. Group – reactivity decreases as you go down the group.

How does reactivity change as you go down a group?

In Metals: Period – reactivity decreases as you go from left to right. Group – reactivity increases as you go down a group In Non-metals Period – reactivity increases as you go from the left to the right. Group – reactivity decreases as you go down the group.

What is the relationship between reactivity and period in metals?

DOWN a Group: In METALS reactivity INCREASES as you go DOWN a Group because the farther down a Group of metals you go, the easier it is for electrons to be given or taken away, resulting in higher reactivity. ACROSS a Period: In METALS reactivity DECREASES as you go ACROSS a Period because though they still want to give away valence…
