The force which helps protons overcome their natural inclination to repel each other is call the strong force. A
Transition metal, any of various chemical elements that have valence electrons—i.e., electrons that can participate in the formation of chemical bonds—in two shells instead of only one.
<h3>What are properties of transition metals?</h3>
The transition metals have the following physical properties in common:
- they are good conductors of heat and electricity.
- they can be hammered or bent into shape easily.
- they have high melting points (but mercury is a liquid at room temperature)
- they are usually hard and tough.
- they have high densities.
<h3>Where are the transition metals?</h3>
Early transition metals are on the left side of the periodic table from group 3 to group 7. Late transition metals are on the right side of the d-block, from group 8 to 11 (and 12 if it is counted as transition metals).

Answer:
For a given amount of gas held at constant temperature, the product of pressure and
volume is constant.
:
Answer: -
6.26 grams
Explanation: -
Atomic Mass of sodium Na = 23 gram
Mass of Na = 18 g
Atomic mass of oxygen O = 16 gram
Molar mass of O2 = 16 x 2 = 32 gram
The balanced chemical equation for the reaction is
4 Na + O2 -- > 2 Na 2 O
From the balanced chemical equation, we see
4 Na requires 1 O2
4 x 23 gram of Na requires 32 gram of O2
18 g of Na gives
= 6.26 grams of O2
For the reaction of formation of Na2O, for 18.0 g of Na, 6.26 grams of O2 are needed for reaction.
The fundamental force holding the nucleus together is the "strong force."
At extremely short range, it is stronger than electrostatic repulsion, and allows protons to stick together in a nucleus even though their charges repel each other.
