Chem 1
A positive subatomic particle located in the nucleus.
What is a proton?
A table that classifies elements by their physical and chemical properties; rows are called periods; columns are called groups
What is the periodic table?
What bonds do metal atoms make with eachother?
What are metallic bonds?
A unit of electrical potential.
What are volts?
I
What is the symbol for current?
A atom missing one or more neutrons.
What is a isotope?
A type of element that shares metal and non-metal properties.
What is a metalloid?
Occurs when a metal “gives“ a valence electron to a non metal electron.
What is a ionic bond.
A continuous conducting path for current
What are circuts?
An electrical component that restricts the flow of electric current.
What is a ressistor?
The outermost electrons that plays huge roles in chemical bonds and reactions.
What are valence electrons?
An area around the nucleus of an atom where electrons are likely to be
What is the electron cloud/energy cloud?
This type of bone forms between when two atoms “link” together to complete each others shells.
What is a covelent bond?
A material that has freely moving electron.
What is a conductor?
(No question format sry)
Electrons always flow from ____ to ____
Negative, Positive
A atom that has lost or gained electrons.
What is an ion?
A colunm on the periodic table.
What is a group?
A type of bonds form between metal and metals making “a sea of electrons”
What is a metallic bond?
A configuration of two or more components connected in a circuit so that the same current flows through each of them.
What is in series?
(couldn‘t do the question type things here sry)
How much does 1 proton weigh?
1 amu
A quality of a substance that can be observed or measured without changing the substance's composition.
What is a physical property?
What type of atoms do ionic use to form
Hint: starts with an I
What is a ion?
A plate or rod (usually metal) in a battery that acquires an electric charge. One end of the electrode functions as a battery terminal.
What is a electrode?
The voltage across a conductor is directly proportional to both the current through it and to the device's electrical resistance. Usually written in the following form: Voltage = Current x Resistance.
What is Ohms law?
