Atomical Electeonics Flashcards
What is an atom?
The smallest part of a chemical element that can exist
What are atoms made of?
Protons, neutrons and electrons
What is a proton
The positively charged part of the nucleus
What is a neutron?
The no charge part of the nucleus
What is an electron?
A negatively charged surround of the nucleus
What is the nucleus
The positively charged center of the atom where protons and neutrons are packed together containing to make nearly all of the atoms mass.
What is the minimum protons an atom can have?
1
What does the number above a chemical element on the periodic table called and what does it represent?
atomic number and atomic mass. The atomic number of an element is the number of protons in the nucleus of an atom of that element. This number determines the element’s identity and its place in the periodic table
Are atoms electrons forever bound to it?
No
What is the name of the electrons on the outer orbit of the atom called?
Valence electrons
Can valence electrons become free and move from atom to atom?
Yes
What is electricity defined as on an atomic level.
The flow of electrons from one place to another?
Why do we use copper in electronics?
The atoms that make copper have loosely bound valence electrons. This meats there are a lot of free electrons to move from one atom to another making it a great conductor to move electricity. (Move electrons from one place to another)
