atomic structure extra notes.
o what type of charge does a proton have?
Positive
o what type of charge does a neutron have?
-neutral
o what type of charge is an electron have?
negative
o which two subatomic particles are located in
the nucleus of an atom?
-Protons + neutrons
what subatomic Particles fly in the clouds
around the outside of the nucleus.
electrons CO
Defination: An atom is a tiny particle in matter, & atoms are made of Protons, nuetrons.
& electrons. Some matter, like your body or your book, is made of lots of different kinds
of atoms, but elements are made up of only one kind of atom.
Key vocabulary
o nucleus
-center of an
atom
o neutron
-neutral electric
charge
o Proton
Positive electric
charge
atom notes
Protons, neutrons, electrons.
oelectron
-Hinest part of all
-1 proton
-lelectron
-#1 on Periodic table.
ooxygen
<-8 Protons
notes:
a atoms are the tiniest things
-only visible through a microscope.
。 water
• Atoms:
- are the tiny particles that make up all matter
o center of an atom is a nucleus
-nucleus made up of
notes (continued) + Periodic Table of elements
o Hydrogen
Protons & neutrons
-2 hydrogen
1 oxygen
water molecule (H²0)
-Protons - POSHive
-neutrons=none
-electrons = finest, runs in circles around the nucleus
-electrons = negative
o number of Protons in atom = number of electrons
8 electrons
-#8 on penodic table
• When 2 atoms combine, it creates a molecule
• Sometimes, when atoms combine, they're all the same atoms.
- an element is created when that happens
of the atoms that combine are different, they're still molecules, but they're called
compounds instead
atoms summary
o atoms are tiny particles that make up all matter
o cant see unless we use microscope
onucleus is at the center of the atom & is made up of Protons & neutrons
o electrons circle around the nucleus
Ownen 2+ atoms combine, its called a molecule
• If the atoms that combine are the same, its an element. If the atoms are
different, its a compound.
• the # of Protons determines the type of atom an element makes
