Chapter Two: Atoms And Elements Flashcards
What is an ionic bond
When one atom STEALS electron
What is the exponent in Electron Configuration for 3d__ 2p__ 1s__
3d 10 2p 6 1s 2
What is an ionic compound
An arrangement of oppositely charged ions arranged so it’s neutral
What does the 3 in 3d10 mean
The 3rd shell in an atom
Define rock
Any solid mass of mineral
Minerals must be
Naturally occurring Solid Same comp through out Well defined chemical comp Inorganic
What is the nucleus made of
Proton neutrons
Is an atom with 6 neutrons 7 protons and 8 electrons stable
No.
What are the atomic number and mass
N-p
M-p+e
Define radioactive decay
Isotope disintegrate through this process
What is the building block all silicates have
Silicon oxygen tetrahedron
What is an isotope
each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
What happens to have an atom produce an ion
The atom either gains or loses an electron. Atoms normally have the same number of electrons(-) as protons(+) so they are neutral, no charge.
What are the two most common elements in earths crust
Oxygen and silicon
What are the two most common silicate minerals
Feldspar and Quartz
