Chemistry Flashcards
What is an Atom?
An atom is the smallest particle in any chemical element.
What is Matter?
Anything that is made of atoms-Solids/Liquids/Gasses/Plasma.
What are Atomic Particles?
One of the particles that an atom is made of- Electron/Neutron/Proton.
What is an Electron?
An electron is the smallest part of an atom and is 0.000000… heavy in the AMU scale, It is found in the shells of an atom and emits an -negative charge.
What is a Neutron?
A Neutron is used to help balance the protons in the nucleus and has a neutral charge; hence the name Neutron. It weighs 1 on the AMU scale.
What is a Proton?
A proton is an atomic particle that also weighs 1 in the AMU scale like the Neutron, and is found in the Nucleus. The Proton has a +positive charge.
What does AMU mean?
AMU is an acronym for Atomic Mass Unit, it is the scale of measurement used to express molecular and atomic weights.
What is an Electron shell
An electron shell is the outside part of an atom, it is around the nucleus.
What is an element?
Each of more than one hundred substances that cannot be chemically broken down into simpler substances. Each element is distinguished by its atomic number; the number of protons in the nuclei of its atoms.
What is a compound?
Something that is made of two or more separate elements that are bonded
What is the Periodic table of elements?
The periodic table of elements is a table that has all the chemical elements arranged in order of atomic number.
There is a total of 118 elements in the table.
What is the Atomic number?
The atomic number is basically the number given to an element in the periodic table of elements that corresponds to the number of protons in the nucleus.
What is Atomic Mass?
Atomic Mass is the weight of an element and it can be found by adding all the particles AMU weight.
What is an Ion?
An Ion is an element that has a full valence shell. Also a charged atom
What is a Cation?
A Cation is a positively charged ion that is created by removing electrons to get a full outer shell. All metals are Cations.
What is an Anion?
An Anion is a Negatively charged ion that is created by gaining electrons to get a full outer shell. All non-metals are Anions. Anions usually had -ide on the end of a particle e.g. Chlorine atom = Chloride Ion
Chemical symbol
The Chemical Symbol is an abbreviation of an elements Chemical name, It is usually the starting letters of it, if necessary to distinguish different elements. if it has a symbol that does not correspond to its current name, it means that it is originated from an older name.
Chemical Name
The chemical name is the name given to each element in the periodic table.
Periodic Law
A law stating that the elements, when listed in order of their atomic numbers, fall into recurring groups so that elements with similar properties occur at regular intervals.
Metalloids
Metalloids are elements that have properties of both metals and non-metals.
Lustre
The shine or radiance of something.
Conductors
Something that can conduct or carry through.
Malleable
Something that can easily be broken or shattered.
Ductile
Something that can be drawn into a thin line.
