C. It is decreased by a factor of 3.
Answer:b. gravitational, kinetic, thermal
Explanation:
The above explains the mechanism of the core forming process on earth/planet.
It is believed that this process might has contributed significantly to a planet's early stages heating. The time when these core-forming event happened is thought to have been mainly completed very early when Earth was young . The type of this event rather than it being seen as a single catastrophic event, it is likely to have been as a result of contractions on the earth severally.
The addition of partially differentiated material from another giant impact the rate of this spasm , and it increases each time the planet's mass is to increased.
This is a little on the history of planetary evolution.
Answer:
A. 1:3
Explanation:
If we look at the ions shown in the image attached to the question, we will notice that we have aluminum (Al^3+), a trivalent ion combining with the iodide ion (I^-).
Aluminum can easily give out its three outermost electrons to three atoms of iodine. If aluminum gives out its three electrons, it achieves the stable octet structure. Iodine atoms have seven electrons in their outermost shell. They only need one more electrons to complete their octet. This one electron can be gotten by the combination of three iodine atoms with one atom of aluminum. One electron each is transferred from the aluminum atom to each iodine atom to form AlI3 with a ratio of 1:3.
Answer: Substance is Mercury (Hg)
number of protons = 80
number of electrons = 80
Explanation:
Atomic number which is symbolized by "Z" is the number of protons in nucleus of an atom.
Hence,
number of protons = atomic number = 80
- By knowing atomic number, we can find the element by using periodic table. Since the atomic number 80, the element is Mercury (Hg).
If the substance is in its neutral state, which means there is no charge on it, then the number of protons equals to the number of electrons of that element.
Hence,
number of electrons = number of protons = 80
