The three main particles that make up an atom.
What is: a proton, a neutron, and an electron?
Group with a full valence shell.
What Is: noble gases(group 18)?
Compound with a higher boiling and melting point than others.
What is: ionic compounds?
Relationship between protons and electrons in a neutral atom.
What is: Protons are positive, and electrons are negative, so if its neatral, then there are the same number of protons as electrons?
The atomic number and mass number.
What is: The atomic number is the number of protons, and the mass is the number of protons and neutrons(electrons don't have any mass because they're too small)
Potassium protons.
What is: 19 protons?
The main difference between ionic and covalent compounds.
What is: Ionic compounds are usually a metal and a non-metal, and covalent compounds are usually from 2 metals?
Ion.
What is: an atom/s while a electrical charge that is either positive(cation) or negative (anion)?
Electronegativity changes as you move down a group in the periodic table.
What is: it decreases?
The difference in reactivity between metals and nonmetals based on their valence electrons.
What is: metals lose valence electrons to become positive ions, while nonmetals gain valence electrons to become negative ions?
Ionic compounds are formed.
What is: A non-metal takes an electron from the metal and becomes negative, while the metal becomes positive. They bond because a negative is attracted to a positive(works like a magnet)?
Atoms become a cation or an anion.
What is: an ion that either loses or gains an electron?
The number of valence electrons influences an element's chemical properties.
What is: the elements in the same group have similar chemical properties, how they bond, and how it becomes stable?
Protons affect an element's place on the periodic table.
What is: the protons are the same number as the atomic number and are in ascending order?
Covalent compounds don't conduct any electricity.
What is: The compound of the two non-metals shares electrons to become neutral
An electron changes the charge of an atom.
What is: it becomes an anion?
The ionization energy of an element affects its ability to form compounds.
what is: it determines an element's probability to lose a cation or an anion?
Noble gases are inert.
What is: They have a full valence electron shell?
Ionic compounds influence their use in batteries.
What is: Because ionic compounds conduct electricity?
It's important to include the charge for the symbol of an ion.
What is: to tell if it's a cation or anion and help with how it'll bond with other ions and atoms?
