beryllium
Strontium and sulfur are both chemical elements, but they are not similar in terms of their properties or behavior. Strontium is a metal that is in the same group as calcium, while sulfur is a nonmetal that is commonly found in compounds like sulfides and sulfates. They have different physical and chemical properties.
Magnesium (Mg) is a member of the alkali earth metals family in the periodic table. This family includes elements with similar chemical and physical properties, such as beryllium, calcium, strontium, and barium.
Chemical properties involve reacting with another substance. IE: burning of magnesium requires oxygen after which it is no longer magnesium. Physical properties do not. IE: metals are malleable, some very malleable, like copper wire can be bent with your hand. BUT it is still copper wire.
Strontium reacts with water producing strontium hydroxide and hydrogen gas. This is a chemical 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.

Mg (magnesium)
The reaction between magnesium and oxygen to form magnesium oxide is a chemical change. This is because new substances with different properties are formed during the reaction.

Yes, the combustion of magnesium, or anything else for that matter, represents a chemical change. For magnesium, the combustion reaction results in the loss of magnesium and the production of magnesium oxide. Clearly a chemical change.

elements in each group of the periodic table have identical chemical properties as they have the same no. of valence electrons which determines their chemical properties. since calcium is in group II of the periodic table, it has the same chemical properties as the elements in group II. Elements in group II consists of: Be, Mg, Ca, Sr, Ba, Ra Elements in the same group has different physical properties such as boiling and melting points. However there are trends of their physical properties down the group.
This is a chemical change, like any other burning reaction: magnesium is turned into magnesium oxide by burning reaction with oxygen (from air). 2Mg + O2 --> 2MgO
PICKLES !
Heating magnesium is a physical process.But the reaction of magnesium with oxygen at high temperature is a chemical process.
