Why do scientists need to see what atoms look like?
So as to explain the properties of atoms.
A combination of two or more atoms that has physical and chemical properties that differ from the atoms that compose it is called?
I'm pretty sure is is a Compound. A compound is a substance that is made up of more than on element. The properties of matter mostly depend on how atoms of different elements are combined in compounds.
How do you know if two atoms are isotope?
They have the same number of protons and therefore the same chemical properties. But they have different numbers of neutrons and so the atomic masses are different and so are some physical properties.
A substance that is formed from atoms with a characteristic set of physical and chemical properties is called what?
A substance that is formed from one type of atoms with a characteristic set of physical and chemical properties is called an element.
How are 2 isotopes of an element similar?
Their atoms have the same number of protons and electrons and therefore have the same chemical properties. However, the atoms do differ in the number of neutrons and so their physical properties are slightly different.
What physical properties are different for the isomers. explain.?
Isomers have different structures even though they have same compounds
What is a combination of two or more atoms and has different physical and chemical properties than its individual atoms?
NaCl, or table salt.
When atoms rearrange to form matter with different properties what type of change has occurred?
physical change
What is different about the isotopes of a particular element?
The number of neutrons in the atoms. This affect some physical properties.
What is meant by the term molecule explain why the term has no meaning for an ionic compound?
The smallest particle of a substance that retains the chemical and physical properties of the substance and is composed of two or more atoms; a group of like or different atoms held together by chemical forces.

Is attraction a chemical property?
Magnetic properties of materials are considered as physical properties.

Is it true that all atoms of hydrogen have the same chemical and physical properties?
No it’s just like a snowflake there are all different

Why do different elements have different properties?
Elements have different properties because elements can be further divided than atoms and can be mixed by another element
