Answer:
D. A compound can be separated into two or more elements through a chemical reaction.
Explanation:
By method of elimination, we are going t obtain the correct option.
A. A compound is made up of a single atom.
This is wrong because, a compound can contain more than one atom. An example is H2O
B. A compound is made up of many atoms that are all the same type.
This is wrong because a compound can contain atoms of different elements. An example is H2O. It contains atoms of hydrogen and oxygen.
C. A compound can be separated into two or more elements through physical processes.
This is wrong. H2O being a compound cannot be separated by ordinary physical means.
D. A compound can be separated into two or more elements through a chemical reaction.
This is the correct option.
Answer:
The correct answer is that it is made of atoms that are covalently bonded together.

Answer:
The isotope notation for an ion of silver-109 with a charge of positive 1 is 
.
Explanation:
The elements with same atomic number with different mass numbers are called isotopes.
The isotopes of silver is as follows.
From the above two isotopes have same atomic number and different mass number.
From the given,the isotope notation for an ion of silver-109 with a charge of positive 1
It can be represented is as follows.
General representation of isotope is as in attachment.
Answer:
Ionic compounds: They have high melting points and boiling points. That is, ionic compounds are non-volatile.
Covalent compounds: They have usually low melting points and boiling points. That is, covalent compounds are usually volatile.
