If all atoms in a sample of matter are alike that kind of matter is?
an element
What kind of carbon atoms does a molecule of pentene have?
There is only one (chemical) kind of carbon atoms, they all are alike.
What is a sample of matter that is either a single element or single compound?
Not very much matter is made up of only one kind of atom. Graphite in pencil leads is a popular one, but most matter is made up of several kinds of atoms.
Does gas have atoms?
Yes. Every kind of matter is made up of atoms.
Atoms of different elements are alike?
no. There is one element for each kind of atom.
How are all atoms similar?
all atoms of the same kind of matter have the same number of protons in them. 🙈
Substance in which all atoms are alike?
A substance in which all atoms are identical is called an element.
Why is a sample of matter considered a pure substance?
A pure substance is either an element or compound. Elements are composed of only one kind of atom, and compounds are composed of a definite proportion of atoms of different elements that is always the same.
What is matter that contains the same kind of atoms in the same combination?
This is a chemical compound.
All substances are made from these?
Atoms! All matter is composed of atoms. Whether it's a pure sample of an element, a compound, or a mixture; solid, liquid, or gas, it all comes down to atoms. The word atom was coined by a Greek thinker named Democritus, who was the first to theorize that all matter was made up of some kind of indivisible particle, which he called "atomos," meaning indivisible. Thanks, Democritus!
What is one characteristic of a sample of matter that indicates it is a pure substance?
A pure substance is a material which contains atoms of only one kind. It has fixed physical and chemical properties like boiling point, melting point, valency, density.
How are all atoms of the same kind of matter similar?
They have the same number of protons in their nuclei.
