ATOMIC STRUCTURE Flashcards
TRUE OR FALSE:
The atom is essentially empty space
TRUE
The __________ reveal how an atom reacts chemically.
The arrangement of the shells
TRUE OR FALSE:
The closer an electron to the nucleus the greater is its electron binding energy.
TRUE
TRUE OR FALSE:
In their normal state, atoms are electrically neutral and the electric charge on the atom is zero
TRUE
It is the removal or addition of an orbital electron of the atom
Ionization
TRUE OR FALSE:
The larger the atom, the greater the abundance of neutrons over protons
TRUE
What is ion pair?
Positive ion and negative ion
What is the formula to get the maximum number of atoms in a shell?
2(n)²
The other term for shell number?
Principal quantum number
The number of electrons in the outermost shell is:
-Equal to its group in the periodic table
-Determines the valence of an atom
The number of the outermost electron shell is:
The period of the element in the periodic table
TRUE OR FALSE:
No outer shell can contain more than eight electrons
TRUE
Electrons that are added into the inner shell instead of adding it to the next outer shell
Transitional elements
The force that keeps an electron in orbit is the…
Centripetal force
The flying out from the center force
Centrifugal force
