Answer:
The isotope with the greatest number of protons is:
- <u>option D: Pu-239, with 94 protons</u>
Explanation:
The number of <em>protons</em> is the atomic number and is a unique number for each type of element.
You can tell the number of protons searching the element in a periodic table and reading its atomic number.
Thus, this is how you tell the number of protons or each isotope
Sample Chemical symbol Element atomic number # of protons
A Pa-238 Pa protactinium 91 91
B U-240 U uranium 92 92
C Np-238 Np neptunium 93 93
D Pu-239 Pu plutonium 94 94
This demonstration is most likely trying to show you potential energy. The rock is heavier than the pebble and will therefore displace more sand upon impact showing that the rock stores more potential energy than the pebble does when they are elevated to the same height (in this case the height is the height of the table).
This makes sense since potential energy is equal to mass times the acceleration due to gravity times height (PE=mgh) and the only thing that is changing is the mass of the object being suspended which means that the heavier object (the rock) will have more potential energy.
I hope this helps. Let me know if anything is unclear.
Answer: The given statement is false.
Explanation:
When there is more difference in the ratio or number of protons and neutrons then nucleus of the atom becomes unstable in nature. This unstability is caused due to greater repulsion between the like charges of sub-atomic particles.
As a result, this force of repulsion becomes greater than the binding energy. And, this force is known as the weak force because it is unable to bind the neutrons and protons together.
The proton and neutron ratio for smaller elements is 1:1 and for higher elements it has to be 1:5. Since, 
is a smaller element with 4 protons and 4 neutrons. Hence, the proton and neutron ratio is 1:1.
Therefore, is stable in nature.
Thus, we can conclude that the statement nucleus of 8Be, which consists of four protons and four neutrons, is very unstable and spontaneously breaks into two alpha particles (helium nuclei, each consisting of two protons and two neutrons), is false.
4 carbon chain is butane. With a triple bond it is butane. Since the triple bond is on the first carbon it can be called 1-butyne, or but-1-yne.
<h2>Answer:</h2><h3>Vitalism-</h3>
- A theory that an organic molecule cannot be produced from inorganic molecules, but instead can only be produced from a living organism or some part of a living organism. The theory was disproved in the early part of the 19th century<em>.</em>
<em>Translated</em><em>~</em>
- Teoría de que una molécula orgánica no se puede producir a partir de moléculas inorgánicas, sino que solo se puede producir a partir de un organismo vivo o de alguna parte de un organismo vivo. La teoría fue refutada a principios del siglo XIX.
