Answer:
There are
electrons in this atom.
Explanation:
Electron configuration of this atom:
.
The electron orbitals of an atom are denoted as
,
,
,
,
, etc. At any given time, an electron in this atom is located in exactly one orbital.
The electron configuration of an atom gives the number of electrons in each orbitals of this atom.
For example, in this atom, the superscript "
" on the right of "
" means that there are two electrons in the
orbital of this atom. Hence,
would translate to:
- The
orbital of this atom contains
electrons. - The
orbital of this atom contains
electrons. - The
orbitals of this atom contain
electrons.
Hence, there would be
electrons in total in this atom.
Answer:
(c.) as the force of Earth's gravity on an object increases, the object's mass increases
Explanation:
Based on newton's law of gravitation "every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of the masses of the particles and inversely proportional to the square of the distance between them".
It is mathematically expressed as:
F = 
F is the gravitational force on either particle
m₁ and m₂ are the masses
r is the distance between particles
G is the universal gravitation constant.
From this expression, we see that the force of earth's gravity is directly proportional to mass.
