C. Usually when an atom loses or gains an electron, it is because it is trying to satisfy the Octet Rule. The Octet Rule states that an atom is at its stablest when it has 8 valence electrons (two in helium's case)
If you look on the periodic table, elements on the left (Alkaline Metals) are the most reactive because they only have one valence electron (or electron in the outer shell). Elements on the right (Noble Gases) are the least reactive because they have a full outer shell of 8 valence electrons.
Later on you will find that as stability decreases as you go down the periodic table but that is a discussion for a different time.
Answer:
This is the definition of slope.
Step-by-step explanation:
The formula for slope is:
m(slope) = (y2 - y1)/(x2 - x1)
This shows the difference in y, which is rise, divided by the different in x, or run.
Answer: By strengthening cardiorespiratory endurance your body will be able to take in and carry more oxygen. This will result in an increased number of red blood cells and hemoglobin. Your heart rate will also become stronger and be able to pump out larger volumes of blood and distribute the oxygen better.
Explanation:
Answer:
• Bring another magnet wound with a copper wire, at the top of the fixed magnet. Here EMF will be generated by mutual induction
Explanation:
Answer:
force is 96 N
Explanation:
given data
mass = 40 kg
acceleration = 2.4 m/s²
to find out
force
solution
we know force is mass time acceleration so
we will apply here force formula that is express as
force = m × a ..............1
here m is mass and a is acceleration so
put here value in equation 1 we get force
force = 40 × 2.4
force = 96
so force will be 96 N
