Proton
How many protons are in Carbon?
There are 6 protons
Where are nonmetals found on the Periodic Table?
The right side, by Halogens and Metalloids
Yes, all elements in a period have the same number of atomic orbitals.
Is Nitrogen and Sulful a Covalent or Ionic Bond?
It is a Covalent Bond
What is an atomic Number?
Protons equal the atomic number
How many nuetrons are in the Isotope- Carbon ~ 14
There are eight nuetrons in Isotope - Carbon ~ 14
What is the difference between an Alkali metal and an Alkaline Earth Metal?
An alkali metal has one electron in the outer shell (+1 charge), which is very reactive and conducts electricity. Alkaline Earth metals have two electrons on the outer shell (+2 charge), conduct electricity.
Is the Periodic table read from left to right?
Yes the Periodic table is read left to right.
Is Boron and Helium an Ionic or covalent bond?

Protons= 1 Neutrons=1 Electrons=1
What is a metalloid?
It is a mixture of nonmetals and poor metals that have properties between them.
Are they grouped in a family with similar characteristics?
Yes, they are Noble gases are together and ext.
Oppositly charged ions attraced to eachother.
(metal and nonmetal)
What are isotopes?
