As each successive element in Group 15 of the Periodic Table is considered in order of increasing atomic number the atomic radius does what?
As each successive element in Group 15 of the Periodic Table is considered in order of increasing atomic number, the atomic radius decreases. This is due to the increasing effective nuclear charge and the filling of electrons in the same energy level, leading to a greater attraction between the nucleus and the outermost electrons.
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.
What is the order of reactivity of alkaline earth metals?
The order of reactivity of alkaline earth metals decreases down the group. This means that the reactivity decreases as you go from beryllium to radium. Beryllium is the least reactive, while radium is the most reactive.
What happens to reactivity of the element as you go left to right?
The reactivity of elements generally decreases as you move from left to right across the periodic table. This is due to the increasing number of protons in the nucleus, leading to a greater attraction for electrons in the outer shell, making it harder for the element to form bonds.
How does increasing temperature affect the solubility of a gas solute?
Increasing temperature decreases the solubility of a gas solute in a liquid solvent. This is because higher temperatures increase the kinetic energy of molecules, leading to weaker gas-liquid interactions and reduced solubility.
What is the reactivity for the halogens?
The reactivity of halogens decreases with increasing atomic number.

Metal reactivity increases from left to right in the periodic table?
No it decreases.
How does increasing the resistance affect the current?
Increasing resistance decreases current.
How does the increasing the resistance affect the current?
Increasing resistance decreases current.
How does increasing the temperature of a gas solvent affect the solubility of a gas?
Increasing the temperature of a solvent decreases the solubility of a gas Generally, increasing solvent temperature decreases the solubility of gases.
The rate at which temperature decreases with increasing altitude is known as?
The rate at which temperature decreases with increasing altitude is known as the lapse rate.
How does the reactivity of each group of metals change across the table from the right?
Reactivity of metals decreases from left to right in the specific period of theperiodic table.
What happens to the reactivity of a nonmetal when you move from left to right in a group?
The reactivity of a non metal decreases as you move down a group. This is because the size of the atomic radius increases and when the distance to the nucleus increases, the force of attraction decreases. Electrons are not pulled as strongly to larger atoms, and so larger atoms are not as reactive.
How does the reactivity of each group of metals change across the table from right to left?
Reactivity of metals decreases from left to right in the specific period of theperiodic table.
