Flashcards in Chapter 2 Chemical Level of Organization Deck (103)
Smallest stable units of matter made up of "subatomic particles"
What are the 3 subatomic particles.
Which subatomic particles are the same size and mass?
-neutrons and protons
Smaller subatomic particle.
Atoms contain a equal number of what subatomic particles.
-Protons and electrons
A equal number of protons and electron give the atom a what charge?
Which subatomic particles are located in the nucleus
Protons & Neutrons
The pathway that an electron follows around the nucleus.
The electron orbit and proton-neutron nucleus make up what?
The number of protons is known as the ______.
The total number of protons and neutrons is known as the ______.
The layering of electrons around the nucleus.
Atoms are classified by the number of protons into groups called ______.
Two or more elements are combined to form _____ _____.
How many elements are in the human body?
13 in large quantities
13 in small quantities
Created in nature by adding additional neutrons to nucleus of element.
Isotopes that emit subatomic paticles or radiation from its nucleus.
This is the time it takes for the radioisotope to breakdown or degrade by half of its original strength.
Quantity of an element that is equal to the elements atomic weight.
Elements that do not react with other atoms are said to be _____. Outer shell is complete.
Elements that interact with other elements are called _____.
What are the types of chemical bonds?
Strong bond when compounds are in solid form but weak when in liquid form.
Two types of ions?
Negatively charged atom.
Positively charged atom.
One atom will lose an electron (electron donor)
One atom will gain an electron (electron acceptor)
Strong bond in which two atoms can complete their outer shell by sharing electrons. Strong bond. Can be single, double, or triple.
