Atomic Structure + Separating Techniques Flashcards
What are the components of an atom?
Protons
Electrons
Neutrons
Which subatomic part is have mass?
Protons and neutrons
What subatomic particles are found in the nucleus?
Protons and neutrons
Where are electrons found in an atom
Orbiting on shells
What are the charges of subatomic particles?
Protons are positive
Electrons are negative
Neutrons are neutral
What is an isotope?
Atoms of the same element with the same number of protons but different number of neutrons
What a does the atomic mass represent?
Total number of protons and neutrons in an atom.
What is the relative atomic mass?
What is an element?
Substances that are only made up of one type of atom
What is an atom?
Smallest part of matter that can take part in a chemical reaction.
What is a compound?
A substance made from two or more different types of atom that are chemically bonded together.
What is the basic structure of the periodic table?
Elements are arranged into columns called groups. These groups contains elements with similar chemical properties. The ‘staircase’ drawn on the right of the periodic table in bold black is the dividing line between metals and non-metals. Those to the right of the liens are non-metals.
What are metalloids?
Metalloids or semi-metals are the elements lying next to the dividing line.
What is the law of conservation of mass?
The total mass of the products formed in a reaction is equal to the mass of the reactants
Solvent
The liquid in which the solute dissolves in.
