<span>A metal is one which ionizes easily and gives electrons whencompared to other elements.
So it should have a lower ionization energy.
Hence we would expect element 2 to be a metal.</span>
Answer:
- <u><em>50% of the offspring will have green pods.</em></u>
Explanation:
Use a upper case to identify the dominant allele and lower case to identify recessive allele.
<em>A homozygous pea plant</em> would be YY or gg. The <em>homozygous recessive pea pleant</em> would be gg (YY is dominant).
<em>A heterozygous pea plant</em> would be Yg (or gY which is the same).
The <em>Punnett Square </em>for the cross between a <em>homozygous recessive pea plant</em> (gg) and a <em>heterozygous pea plant</em> (Yg) would be:
g g
Y Yg Yg
g gg gg
Hence, <em>the offspring will have</em> two Yg, which would be yellow pods, and two gg which would be green pods.
That is, 50% of the offspring will have yellow pods and 50% will have green pods.
Answer:
Explanation:
Double Bond => An Alkene molecule
So, the suffix will be "-ene"
7 Carbons => So, we'll use the prefix "Hept-"
Combining the suffix and prefix, we get:
=> Heptene
<h3><u>Answer;</u></h3>
only in the n = 3 energy level
<h3><u>Explanation;</u></h3>
- <em><u>The atom of a chemical element is made up of sub-atomic particles which are the neutrons, protons and electrons.</u></em> The neutrons and protons occupies the nucleus of an atom while the electrons occupy the energy levels.
- <em><u>The first energy level (n=1) of an atom occupies a maximum of two electrons because it has only an S-orbital which can only have two electrons.</u></em>
- <u>The second energy level (n=2) can have a maximum number of 8 electrons, since it contains, one S- orbital which can hold two electrons, and a p-orbital which can accommodate six electrons.</u>
- <em><u>The third energy level (n=3) can have a maximum number of 18 electrons,</u></em> because it has <u><em>the S-orbitals which holds 2 electrons, the p-orbital which holds 6 electrons and the d-orbital which holds 10 electrons. </em></u>
