How do elements change going down the periodic table?
Down a group, the atomic number generally increases, size increases, ionization energy decreases, reactivity increases.
Is the reactivity of the metal elements generally increase as you move from left to right across the periodic table true or false?
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.
How does reactivity increase on the periodic table?
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.
What happens to the reactivity as you move down group 1 in the periodic table?
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.
What happens as you move down the family on a periodic table the reactivity?
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
What increases on the periodic table?
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.
Metal reactivity increases from left to right in the periodic table?
No it decreases.
What is the pattern of reactivity observed in the non-metal elements in groups 13-17 of the periodic table?
The reactivity of non-metal elements generally decreases as you move from left to right across groups 13-17 of the periodic table. This is because the elements have an increasing number of valence electrons and are closer to achieving a stable electron configuration. Non-metals in group 17 (halogens) are the most reactive due to their high electronegativity and affinity for gaining electrons to achieve a full outer shell.
What is the trend in ionization energy of period 3 elements on the periodic table?
The trend in ionization energy of period 3 elements on the periodic table generally increases from left to right.
What are the rules for reactivity of metals on the periodic table?
The reactivity increases with increasing numbers of electron shells (energy levels).
What is the reactivity called when you move from left to right on the periodic table?
The reactivity generally decreases as you move from left to right across the periodic table. This is because elements on the right side tend to have more electrons in their outer shell, making them less likely to form bonds with other elements.
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.
