What else can I help you with?
Why do the properties of an anion differ from those of its parent atom?
The anion has a negative electrical charge and is more chemically reactive than the atom.
Which atom is more chemically reactive an atom with a partly filled energy level or an atom with all energy levels completely filled?
the one that is completely filled
Which is more reactive barium or cesium?
Cesium is more reactive than barium. Cesium is located lower down in Group 1 of the periodic table, making it more reactive than barium, which is further up the group. Cesium readily reacts with air and water, while barium is less reactive in comparison.
Which is more reactive barium magnesium or beryllium?
Barium is more reactive than magnesium, and beryllium is less reactive than both. Reactivity generally increases as you move down a group on the periodic table, so barium is more reactive than magnesium due to its position in the same group.
How can you tell if an atom is chemically reactive or not?
Chemically reactive atoms typically have one or more outer shell electrons that are not tightly bound. Atoms with a full outer shell are usually stable and less likely to react with other atoms. The reactivity of an atom can also be influenced by its position in the periodic table and its electronegativity.
Which is more reactive sodium or barium?
sodium because it's the first group and first group are the most
Which atom is more chemically reactive an atom with a partly filled energy level or an atom with all energy levels completely filled and why?
If all the electron orbitals are filled then the atom is inert. It will not chemically react with anything. If an atom has empty spaces in the outer orbit, it will react with other elements. Electrons from other elements can share positions in the outer orbits.
Do calcium and barium have similar or different reactivities?
Calcium and barium have different reactivities. Barium is more reactive than calcium because it has a greater tendency to lose electrons and form positive ions in chemical reactions. Calcium is a moderately reactive metal that readily forms compounds with oxygen and water, but it is not as reactive as barium.
How is a nitrogen atom different from a nitrogen molecule?
A single nitrogen atom can be chemically reactive while a nitrogen molecule is relatively stable and tends to be faf more inert. A nitrogen molecule also has twice the mass of a nitrogen atom.
What is silver plus barium?
The reaction between silver and barium typically forms silver nitrate and barium nitrate. Silver and barium are both metals and can undergo a single displacement reaction where the more reactive metal, in this case, silver, displaces the less reactive metal, barium, in the compound.
Why Ba is more reactive than Ca?
strontium is more reactive than calcium because it is more electropositive. valance electrons of strontium are farther away from the nucleus of strontiium atom than the valance electrons of calcium from nucleus of calcium atom. so the force exerted by the nucleus on the valence electron of strontium is lesser than that exerted by calcium. so the strontium atom can loose its valance electrons more easily. therefore strontium is more electropositive and more reactive than calcium.
Which element would be most reactive be sr or ba?
Barium (Ba) would be more reactive than strontium (Sr) because barium is located further down the Group 2 elements in the periodic table. As you move down the Group, the reactivity of the elements tends to increase due to the larger atomic size and lower ionization energy, making barium more reactive than strontium.
