The Structure the atom
What are all the different parts of the atom and what do they change?
Protons: The mass number and the total amount of charge
Electrons: Total amount of charge
Neutrons: the mass number
What is an isotope and an Ion?
Isotopes are more of a few neutrons that change mass. Ions are more or less electrons than protons.
Where are the Metalliods found?
Found in the zigzag line on the periodic table
How many elements are on the periodic table?
118
What is a Covalent bond form?
When atoms share electrons
Are protons a positive or negative charge?
Positive, Negative is electrons
Neutrons would be 9
Name one of the Metalloids.
Boron, Silicon, germanium,arsenic, antimony, tellurium, and polonium
What do you call the rows and the columns on the periodic table?
Rows: Periods
Columns: Families
What is an ionic bond
Opposite charged Ions are attached
What do you call the center of the atom? (where protons and Neutrons are)
The Nucleus
What would be the neutrons if sodium has 11 protons and a mass of 23
12
What is located on the right of the periodic table and is a poor conductor of electricity and heat?
Nonmetals
What is the 1st family called?
Alkali metals
what groups (non-metal, metal, metalloids) are part of a covalent bond
non-metal+non-metal
True/False do electrons travel in a perfect circle around the nucleus?
No, they travel randomly around the nucleus
What would be the electrons S-2 (S=Sulfur) with a mass of 32? (16 protons 16 Nutrons)
18 electrons
What is the only metal in the zigzag that is not considered metalloids?
Aluminum
What makes the Noble gas family stable?
It is stable because all its rings are filled up and they have no extra electrons on the rings.
What two ones (Malloids, nonmetals, metals make up an Ionic bond?
Metal+non-metal
What are the rings of an atom called (where electrons are)
Orbital
What is the symbolic notation for Hydrogen-2
2H 0r 2/1H
What is the only metal that is not a solid at room temperature?
Mercery
How many electrons does Helium have if it is in the noble gas family?
2
Name a covalent bond.
Convalent: Carbon dioxide
