Answer:
Chemical formula.
Explanation:
A chemical formula have fix proportion of atoms of elements.
Chemical formula:
A chemical formula is the way of presenting the chemical proportion of atoms of those elements, that combine to form a compound.
For example:
Water consist of two atom of hydrogen and one atom of oxygen. The atoms of both elements combine to form a compound i.e water. The atoms of both elements always combine in a fixed ratio which is 2:1 in molecule of water.
H₂O
2:1
Carbon dioxide consist of two atom of oxygen and one atom of carbon. The atoms of both elements combine to form a compound i.e carbon dioxide. The atoms of both elements always combine in a fixed ratio which is 1:2 in molecule of carbon dioxide .
CO₂
1;2
The moment the question mention Diamond, suspect Carbon as the answer. (1) element: C, carbon. Atomic number: 12 (double check on periodic table). (2) Not sure what does the question means, but I guess in the first shell, there will be 2 electrons and the 2nd shell will have 8 electrons (may need to explain it based on electron configuration involving s,p,d and f orbitals). (3) MOST undergoes sharing of electron so they form covalent bond with non metals.
Global warming and climate change can cause habitats to no longer suit animals needs and not all animals can easily adapt. Climate change can kill if severe enough
