Is adding magnesium to acid a chemical change?
Yes, because the chemical structure is compromised
Why is putting magnesium in water a chemical change?
Magnesium is highly reactive to water because of the atom's electron arrangement. The products of the reaction are, heat, light, and gas, which are all indicators that they had undergone a chemical reaction.
Is burning a magnesium ribbon a physical change?
Burning a magnesium ribbon is a chemical change because the magnesium reacts with oxygen in the air to form magnesium oxide. This results in a new substance being formed with different chemical properties than the original magnesium ribbon.
Is magnesium physical change or chemical change?
Magnesium is not a change of any sort. It is a metallic element that can undergo both physical an chemical changes.
Is adding magnesium and heat chemical or physical change?
Heating magnesium is a physical process.But the reaction of magnesium with oxygen at high temperature is a chemical process.
What change in electron structure occures when a sodium atom becomes a sodium ion?
The valence electrons are either lost to another atom or the sodium atom gains valence electrons, it really depends on if what the sodium atom is bonding with has a lot or a little of valence electrons. The structure doesn't change though, just the number of valence electrons change. The nucleus is never changed when an ion is formed.
How will electron configuration of the atom change when the atom becomes an ion?
When an atom becomes an ion, it gains or loses electrons to achieve a full outer electron shell, resulting in a change in electron configuration. For example, a neutral sodium atom (1s2 2s2 2p6 3s1) loses one electron to become a sodium ion (1s2 2s2 2p6). The electron configuration of the ion reflects this change in the number of electrons.

How does the behavior of an electron change when it forms a covalent bond?
When an electron forms a covalent bond, it becomes shared between two atoms, leading to a more stable arrangement. This sharing of electrons can change the electron's behavior by influencing its movement and interactions with other atoms in the bond.
What happens when a atom gains an electron?
When an atom gains an electron, it becomes negatively charged and forms an anion. This process is known as reduction, and it can change the chemical properties of the atom by affecting its reactivity and ability to form bonds.
What happens with phenothalein is placed in Magnesium hydroxide?
Phenolphthalein in a solution containing magnesium hydroxide would remain colorless as it does not change color at a basic pH, where magnesium hydroxide is present. Phenolphthalein changes color in acidic solutions, not basic ones.
How does the process of melting magnesium affect its properties and applications?
When magnesium is melted, its properties change because it becomes a liquid instead of a solid. This can make it easier to shape and mold into different forms. The melted magnesium can be used in applications such as casting, welding, and as a coating for other materials.
What change in electron structure occur when Mg atom become a Mg ion?
Magnesium is a group 2A element, and has 2 valence electrons. Thus, for it to become an ion (Mg^2+) is loses those 2 valence electrons.
Is burning a magnesium ribbon a physical change?
Burning a magnesium ribbon is a chemical change because the magnesium reacts with oxygen in the air to form magnesium oxide. This results in a new substance being formed with different chemical properties than the original magnesium ribbon.
When magnesium is burnt in the air is it a chemical change?
Yes. Magnesium burns in air brightly giving Magnesium oxide, witch is a chemical change.
