Atom Structure
The positive particle that is found in the nucleus of an atom.
What is a Proton
These are counted vertically on the periodic table and give you the amount of valence electrons
What are Groups
Different varients of an element because it varies in the amount of neutrons.
What is an Isotope
A type of bond that forms when electrons are transfererred from one element to another.
Ionic bond
Which Group is non-reactive?
Noble Gases
because they already have 8 valence electrons in their outer shell.
The neutral particles of an atom found in the nucleus of an atom.
What is a Neutron
This is an alkali metal located in period 2
Li or Lithium
Sodium has a atomic number of 11 and a mass number of 23.
How many neutrons does it have?
What is 12.
When a negative Ion is formed
Anion
What element is liquid at room temperature and was used in thermometers in the past.
Mercury
Was band from thermometers due to mercury poisoning.
The negatively charge particles that are located in the outer most electron shell. These greatly impact how atoms react with other atoms.
What is valence electrons.
This is a noble gas in period 5
Xe or Xenon
Most atoms need to have ______ electrons in their electron shell in order to be stable.
What is 8.
When a positive Ion forms
Cation
What two element make up table salt?
