As we move from left to right across a row on the Periodic Table, the number of protons increases. This increase in protons leads to a greater positive charge in the nucleus, which attracts electrons more strongly, resulting in a decrease in atomic size. Additionally, the chemical reactivity of metals generally decreases, while the reactivity of nonmetals tends to increase.
What else can I help you with?
How does reactivity change down the group of atoms?
Reactivity generally increases down a group of atoms. This is because as you move down the group, the atomic radius increases and the valence electrons become further from the nucleus. As a result, the valence electrons are less strongly attracted to the nucleus, making them more easily available for bond formation and chemical reactions.
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 increases as particle size increases?
As particle size increases, the surface area-to-volume ratio decreases. This can lead to a decrease in reactivity for certain chemical processes, as fewer surface sites are available for interactions. Additionally, larger particles may settle more quickly in a fluid due to increased gravitational forces acting on them. Thus, various physical and chemical properties can change with increasing particle size.
Is chromuim reactivity chemical properties?
Reactivity is a chemical property.
What is a chemical property length color reactivity mass?
Reactivity is a chemical property.
As the elements in Group 17 are considered in order of increasing atomic number the chemical reactivity of each successive element decreases increases or remains the same?
As you move down Group 17 (halogens) from top to bottom, the reactivity decreases. This is due to the increasing atomic size and electron shielding, making it more difficult for the outer electron to be gained by the lower elements in the group, thus decreasing their reactivity.
What is the pKa of an ester and how does it affect its reactivity in chemical reactions?
The pKa of an ester is typically around 25. A lower pKa indicates a stronger acid and higher reactivity in chemical reactions. Ester reactivity increases as pKa decreases, making it more likely to undergo reactions.
How does reactivity change down the group of atoms?
Reactivity generally increases down a group of atoms. This is because as you move down the group, the atomic radius increases and the valence electrons become further from the nucleus. As a result, the valence electrons are less strongly attracted to the nucleus, making them more easily available for bond formation and chemical reactions.
How does chemical reactivity change as you move across the periodic table?

Electro chemical series down the group increases or decreases?
It increases
What is the relationship between the atomic radius of chromium and its chemical properties?
The atomic radius of chromium affects its chemical properties. As the atomic radius decreases, the attraction between the nucleus and electrons increases, leading to changes in reactivity and bonding behavior.
What is the relationship between the ionic radius of magnesium (Mg) and its chemical properties?
The ionic radius of magnesium (Mg) affects its chemical properties. As the ionic radius decreases, the attraction between the nucleus and electrons increases, leading to higher reactivity and stronger bonding with other elements. This can influence properties such as solubility, melting point, and chemical reactivity of magnesium compounds.
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 as particle size increases?
As particle size increases, the surface area-to-volume ratio decreases. This can lead to a decrease in reactivity for certain chemical processes, as fewer surface sites are available for interactions. Additionally, larger particles may settle more quickly in a fluid due to increased gravitational forces acting on them. Thus, various physical and chemical properties can change with increasing particle size.
How does reactivity work with the elements when you go down the groups?
Reactivity tends to decrease as you go down a group in the periodic table. This is because as you move down a group, the valence electrons are further from the nucleus and are shielded by more inner electron shells, making it harder for the outer electrons to participate in chemical reactions.
Why reactivity decreases across a period?
Reactivity decreases across a period because the outermost electrons are held more tightly by the increasing nuclear charge, making it harder for atoms to lose or gain electrons to form compounds. This results in a decrease in chemical reactivity as you move from left to right across a period.
Is reactivity a chemical change?
Reactivity is not a change; it is a chemical property.
