Antimony
All except neon, with atomic symbol Ne, of the entities shown the question by their chemical formulas or symbols can be decomposed by chemical change.
Ne - neon, is an element and also a noble gas. It can not be decomposed by a chemical reaction. All the other substances can be.
No. Sodium is an element and elements cannot be broken down (decomposed) by a chemical change.
No
False. This is a chemical change. A physical change is, for example, when Ice melts into water. It is the same element but it is in a different form. A chemical change is, for example, when two hydrogen atoms and an oxygen atom come together to form a water molecule, thereby producing a new substance.

If you are not concerned about atoms, electrons, neutrons, protons and other sub atomic particles, but confine to chemical substances occurring in nature or man made, the substance that cannot be broken into simpler substances is an "element" (usually enumerated in a periodic table).A chemical element cannot be decomposed into a simpler substance.Elements. They are defined as substances in their simplest form and cannot be broken down or decomposed into any simpler substances. They include all elements in the periodic table of elements.
No. Fe (iron) is an element, the simplest type of chemical substance possible, and so it cannot be broken down by chemical means.
No. Sodium is an element and elements cannot be broken down (decomposed) by a chemical change.
methanolammonia (NH4)ammonia (NH4)
Rotting wood is a chemical change because the decomposed wood has different properties that cannot be reversed. Chemical changes alter the identity of a substance, whereas physical changes do not.

Chemical property, it cannot be decomposed by ordinary chemical change.
it is chemical property. they use the word decomposition immaterially shows changein chemical composition.hence chemical change.
