The electron cloud is split up in 3 areas.
1) Inner Electron Cloud
2) Outer Electron Cloud
3) Valence Electrons
Your inner cloud is the electrons CLOSEST to the nucleus.
Your outer cloud is the electrons in the MIDDLE of the Inner and Valence.
Your valence electrons are the OUTER LAYER of electrons. These electrons are important to bonding, and also are what decide where on the periodic table of elements. For example:
197
Au
79
This element is GOLD. It has 1 valence, therefor it is where it is in the period. Ionization could change this number however.
Yes its bigger than 5 millimeters
Answer:
Satellites don't fall from the sky because they are orbiting Earth. Even when satellites are thousands of miles away, Earth's gravity still tugs on them. Gravity--combined with the satellite's momentum from its launch into space--cause the satellite go into orbit above Earth, instead of falling back down to the ground.
Answer:
The pressure increases by a factor 8
Explanation:
For a gas held at constant temperature, Boyle's law can be applied. It states that the product of the gas pressure and the gas volume is constant, so we can write:
where
is the initial pressure
is the final pressure
is the initial volume
is the final volume
For the gas in this problem, the volume is reduced from
to
so we can rewrite the equation as
this means that the pressure of the gas will increase by a factor 8.
Answer:
Parallel
Explanation:
The work done is defined as the force applied on an object and the displacement in the position of the object in the direction of force.
W = F s cos A
where, F is the force, s is the displacement and A is the angle between force and displacement.
When the angle between the force and the displacement is 90 degree, the work done is zero.
To get the maximum work the angle between the force and the displacement is 0 degree.
So, to get the work done by the force the angle between the force and displacement is 0 degree that means the force and displacement is parallel to each other.
