Rather than to give a simple number as answer, I suggest to look up Magnesium on wikipedia, where you will even find a picture with the electron configuration. (And this method can be applied to answer the same question for any other element.)
You look at trends. An element is likely to have properties somewhere between the element above it and the element below it; if there's nothing below it (or above it), then you can follow the general trend up (or down) that column and extrapolate.
Magnesium, calcium, strontium, barium and radium have similar properties to beryllium. All the elements in group two of the periodic table have the same or similar properties. This is because they have the same number of electrons in their outermost shell.
magnesium looks like gold bars but it is grayish sliver
A pure substance of an element consists of only one type of atom, which means it has a uniform composition and distinct chemical properties. It can be found in various forms, such as solids (like iron or gold), liquids (like mercury), or gases (like oxygen or nitrogen). In its purest form, it maintains consistent physical and chemical characteristics throughout. For example, a sample of pure gold will have the same properties regardless of its shape or size.
All you have to do is look at which group Beryllium is in and look at the other elements that are in the same column. The gruop of an element can help you determine its chemical properties. That group would be Group 2 with Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium.
In the same column.
magnesium look like white powder after burning in air. magnesium burns in air n react with atmospheric oxygen n forms magnesium oxide which is a white powder.

Yes, burning magnesium is a chemical change because it involves a chemical reaction where the magnesium combines with oxygen in the air to form magnesium oxide. This results in the formation of new substances with different chemical properties.
Does it look like i no!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
They look like any normal particle, only seen when magnified but even then you can't really describe it.
it is colorless
