Which statement describes J.J. Thomson’s plum-pudding model of the atom?A. The electrons take up most of the space in an atom.
B. The electrons in the atom orbit around the protons.
C. The electrons are embedded in a positive sphere.

Answers

Answer 1

Answer: Option C: the electrons are embedded in a positive sphere.

As we know that was a wrong model and nowadays the electrons are considered to be around the nucleus, in regions called orbitals.

C. cooled magma sinking in a lava flow
D. a hot air balloon falling as the gas inside cools

Answers

A is the answer.

Ice is solid, however, water is liquid. Yet ice still floats which is less dense than water.

Final answer:

Gold is a malleable metal, able to deform without breaking when hammered. On the contrary, Iron Pyrite or 'Fool's Gold' is brittle; it shatters when struck due to its lack of malleability.

Explanation:

Gold is known as a malleable metal, which means it can be hammered or bent into different shapes without breaking. In contrast, Iron Pyrite, often known as 'Fool's Gold', is brittle, meaning it will shatter or break when struck by a hammer.

Malleability is a physical property of metals that allows them to be hammered or rolled into thin sheets. Gold is one of the most malleable metals and can be hammered into extremely thin sheets.

On the other hand, a brittle material like Iron Pyrite lacks this property of malleability. Instead of deforming under stress, it will fracture, this is why it shatters into many pieces when struck.
