Periodic Table 1
The electrons in the outer energy level
What are valence electrons?
A part of an atom with a negative charge
What is an electron?
The atomic number tells you
What is the number of protons (and electrons) an atom of an element has?
Atomic mass - Atomic number
What is the formula for finding the neutrons of an atom?
Formed when Atoms Give or Take Electrons
What is ionic?
The location of protons and neutrons.
What is inside the nucleus?
An atom with a completely full outer most (valence) energy level is this.
What is nonreactive or noble gases?
Tiny particles that make up all matter.
What are atoms?
Arsenic (As) has 33.
What are protons and electrons?
Formed when atoms share electrons.
Covalent?
Columns on a periodic table
What are groups?
The term that refers to the same type of element with different number of neutrons
What are isotopes?
Rows on the periodic table
What are periods?
Arsenic (As) has 42.
What are neutrons?
NaCl is an example of this bond
What is ionic
This group contains the most reactive non-metals
What is group VIIA or the Halogens?
A part of an atom with a positive charge
What is a proton?
The majority of the elements on the periodic table are this.
What are metals?
When an atom loses an electron it is called a
What are cations?
CO2 Is an example of this type of Bond
What is Covalent
Found in a zigzag line on the periodic table.
What are metalloids?
The modern periodic table is organized according to this.
What are by increasing atomic number?
Elements in group 1 have only 1 valence electron and are considered this.
What are elements that are considered extremely reactive?
When an atom gains an electron it is called a
What is Anion?
When we think of molecules they are made of this type of bond.
What is covalent
