what is a period?
The radius of an atom. The distance from the center of the nucleus to the most probable location of the outermost valence electron in an atom. A common unit is a picometer
What is the atomic radius?
A pure substance that is made of more than one type of atom bonded together. Electrically neutral.
What is a compound?
Charged particles formed when atoms or groups of atoms lose or gain electrons to achieve more stable electron configurations
What is an Ion?
the metal atoms in a metallic solid contribute their valence electrons to form a sea of electrons that surrounds the metal cations in their lattice
What is electron sea model?
is the name for the vertical column in the periodic table
What is a group?
Charged particles form when an atom or a group of atoms loses or gains electrons.
What is Ions?
The force that holds two atoms or ions together.
The electrostatic force that holds oppositely charged particles together.
What is an Ionic Bond?
Valence electrons that do not belong to a particular atom but are free to move in the sample.
What are delocalized electrons?
tend to be gray/silver, shiny, malleable, ductile, solids that are good conductors. They are located to the left of the stair step line but do not include hydrogen
What is metals?
the radius of an ion- the distance from the center of the nucleus to the most probable location of the outermost valence electron in an ion. A common unit is a picometer.
What is the Ionic Radius?
What is a Ionic Bond?
a charged particle formed from a single atom
What is a monatomic ion?
The attraction of metallic cation for delocalized electrons
What is a metallic bond?
variety of colors. Usually, they are gases or brittle, dull-looking solids. They are insulators and poor conductors of heat and electricity.
What is nonmetals?
The energy required to remove the most loosely bound electron from a gaseous atom, turning it into a cation with a positive charge
What is the first ionization energy?
a chemical bond that results from the sharing of valence electrons, frequently between nonmetal atoms or between a metalloid and a nonmetal.
What is a covalent bond?
Positively charged ions
What is cations?
What is an alloy?
The most abundant element in the human body
What is oxygen?
the relative tendency of an atom to attract the electrons involved in a chemical bond with another atom.
What is electronegativity?
What is a metallic bond?
Negatively charged ions
What are anions?
