Answer:
m = E × Q
And Q = I × t
m = E × I × t
Where m = mass in grams
Q = quantity of electricity in coulomb
I = current in ampere
t = time in seconds
E = electrochemical equivalent of the substance
Explanation:
They use models when they are trying to find stuff in the ground like fossils so they match them up so they can find if it’s the same or not please mark brainliest must appreciated !
Answer:
Nitrogen is inert because its p-subshell is half-filled due to it has maximum exchange energy. Thus it is exists in stable form as like inert gas and it form triple bond (N≡N). N2 molecules is very stable and its dissociation energy is 225kcal/mol.

Answer:
.
Explanation:
Electron orbitals in an atom (e.g., 
) are denoted with:
- A number, denoting the shell (principal energy level) of this orbital, and
- A letter, denoting the shape of this orbital (
, 
, 
, etc.)
There are two aspects to consider when finding the electron configuration of an atom:
- The number of electrons that each type of orbitals could hold, and
- The order in which the orbitals are filled.
The orbital in each shell could hold up to 
electrons (one 
orbital per shell, with up to two electrons.)
The orbitals in each shell could hold up to 
electrons (three 
orbitals per shell, with up to two electrons in each orbital.)
The orbitals in each main shell could hold up to 
electrons (five 
orbitals per shell, with up to two electrons in each orbital.)
Refer to the order in which the orbitals are filled (Aufbau principle.)
- The first orbital to be filled would be (the orbital of the first shell,) accommodating up to
electrons. - The second orbital to be filled would be
(the orbital of the second shell,) accommodating up to electrons.
All four electrons of Beryllium are thus assigned to the and orbitals. In a ground-state Beryllium atom, orbitals 
and beyond would contain no electrons.
Notation:
- Two electrons in the orbital:
(the superscript denotes the number of electrons in this orbital (or group of orbitals).) - Two electrons in the orbital:
.
Write the non-empty orbitals in the order by which they are filled:
.
