Periodic Table 1
The electrons in the outer energy level
What are valence electrons?
Rule that states “in a degenerate orbitals, the electrons must fill the available orbital first before pairing”.
What is Hund's Rule?
The atomic number tells you
What is the number of protons ?
An atom with a positive charge.
What is a proton?
A subatomic particle with no charge.
What is a neutron?
The group name of elements F, Cl, I, Br and At.
What is Halogens?
An atom with a completely full outer most (valence) energy level is this.
What is noble gas?
Tiny particles that make up all matter.
What are atoms?
Found in a zigzag line on the periodic table.
What are metalloids?
The location of electrons.
What is outside the nucleus?
Atomic mass - Atomic number
What is the formula for finding the neutrons of an atom?
8
What is the maximum number of electrons the 2nd orbital, or energy shell, can hold?
Rows on the periodic table
What are periods?
Columns on a periodic table
What are groups?
Elements in the same group share this.
What are the same number of valence electrons
Number of valence electrons in the elements of Group II A
What is 2?
Kind of element that has high electronegativity
What is nonmetal?
The majority of the elements on the periodic table are this.
What are metals?
The group number and period number of the element which has an electron configuration of 1s2 2s2 2p63s1.
What is Group IA, Period 3?
The three classes of elements are these.
What are metals, metalloids, and nonmetals?
Rule that states “ in an orbital there should be a maximum of 2 electrons and they must be in opposite spins”.
What is Pauli's Exclusion Principle?
The modern periodic table is organized according to this.
What are by increasing atomic number?
Property of metals which refers to bendable.
What is malleability?
The ability of an atom to attract electrons towards itself.
What is electronegativity?
Located on the right side of the zigzag line.
What are nonmetals?
