Atomic Structure Flashcards
It is the building blocks of atoms; very small (protons, neutrons and electrons)
Subatomic Particles
Contains majority of the mass of atoms (protons + neutrons) additional info: electrons occupy almost all volume of the atom since it is located outside.
Nucleus
Any subatomic particles found inside the nucleus(protons and neutrons)
Nucleon
Nucleus - _____
Atoms - ______
Subatomic particles -______
electrons - ______
Mass
Matter
Atoms
Volume
Can be designated as the number of protons and it is designated as the symbol Z
Atomic Number
Value of Z determines the ______ of the atom.
Identity
It is the total # of protons and neutron, designated as the symbol A
Mass number
If the number of subatomic particles are not equal it is called?
Ion
It is positively charged and loses electrons.
Cation
It is positively charged and loses electron.
Cation
It is a negatively charged and gains electrons
Anion
Atoms lose or gain electrons so that they have an electron configuration similar to that of?
Noble Gases (really stable)
How do you 23 Na?
Sodium 23
It is the average mass of all atoms in an element, weighted average of all isotopes x abundance of isotope.
Atomic mass
______ 2 or more atoms that function as a unit, it can be same or different kinds of atoms.
Molecules
It is 2 pair of molecules (h2, N2, O2, F2, Cl2, Br2, I2)
Diatomic (Have No Fear Of Ice Cold Bear)
_____ is 1 same kind of atoms in a molecule.
Homoatomic
________ different kinds of atoms in a molecule
Heteroatomic
_________ rule is that it follow all noble gases that have 8 valance electrons and is achieve through losing or gaining electrons.
Octet
What group usually loses electrons
Group 1A to 3A
What group usually accepts/gain electrons?
Group 4A to 7A
______ it is a formula where the number of atoms of each element in a compound
Chemical Formula
It is the true formula wherein it has the exact number of atoms
Molecular Formula
It is the formula wherein it’s simples whole-number ratio of the number of atoms, it is divided by its lowest common denominator m.
Empirical formula
It is the formula of how atoms are arranged and which atoms are bonded to one another. It is visually drawed.
Structural Formula
Compounds of the same chemical formula but different molecular structures.
Isomers (structure has something to do with properties)
______ _______ is the attractive force that holds atoms together.
Chemical Bond
It is a type of bond where the transfer of electrons from one to another (positive and negative ions)
Ionic bond
It is the type of bond where there is sharing of electrons between 2 atoms
Covalent Bond
