A basic oxide will be formed by the element
You seem to be expecting others to do your thinking and writing for you.
If you include what YOU THINK, a science tutor might be able to help, but you need to do some thinking first.
Your sentence isn't complete. Which element? What are the conditions?
Options are
1. Sulphur
2.potassium
3.phosphorus
4.carbon
To find out which element will form a basic oxide, you need to understand the concept of acid-base reactions and the properties of oxides.
An oxide is a compound comprised of one or more oxygen atoms and one or more atoms of another element. Oxides can be classified as acidic, basic, or amphoteric, based on their reaction with water.
Basic oxides are oxides that react with water to form a base. They typically have a higher pH value and can neutralize acids. Basic oxides are usually formed by elements on the left side of the periodic table (the alkali metals and alkaline earth metals) and some metals from the transition metals group.
To determine which element will form a basic oxide, you need to look at the periodic table. Elements on the left side, such as sodium (Na), potassium (K), calcium (Ca), and magnesium (Mg), are known to form basic oxides. For example, sodium forms sodium oxide (Na2O), which reacts with water to produce sodium hydroxide (NaOH), a strong base.
So, to answer your question, any of the alkali metals (such as sodium, potassium, etc.) and alkaline earth metals (such as calcium, magnesium, etc.) will typically form basic oxides.
