Answer: The aluminum atom loses electrons to form an ion.
The ion that is formed is <u>positive</u>
<u></u>
<u>Second Part of the question:</u> What is the name of the aluminum ion?
<u>
</u>Answer : <u>Al+3</u>
Explanation: <em>An aluminum ion has a charge of +3. It is not a neutral atom. It has a + charge, the electrons must have been taken away (electrons have a negative charge). Since the atomic number is 13, the number of protons is thirteen. In a neutral atom, there would be thirteen electrons. You take away 3. There is 10 electrons in Aluminum Ion. </em>
Answer:
C-14 from fossil had reached itshalf life
Explanation:
For radiactive isotopes (such as Carbon-14), per definition; the semi life or semi disintegration period; is defined as the time for which a certain mass isotope mass disintegrates to half of the atoms that make it up
For Carbon-14, this semi life period is 5730 years , and for the above example, as it is mentioned that we originally had 254 grams of C-14 but we currently have 127 grams (this is, exaclt half of the original mass of 254 grams), this leads us that 5730 years have passed since the original mass and the final mass (that is, one semi life period of C-14)
Answer: Genome is the haploid set of chromosomes in a gamete or microorganism, or in each cell of a multicellular organism. Replicative is relating to or involving the replication of genetic material or living organisms.
Explanation:
So Replicative Genoes are genomes that are able to replicate its own genetic material.
Answer:
Some organs are both a source and sink. Leaves are sinks when growing and sources when photosynthesizing. Rhizomes are sinks when growing but become sources in the spring when they provide energy for new growth.
