Atomic Structure of 14 Elements Please use the periodic table of elements to answer the questions below. How can you determine t
he number of protons in the nucleus of an atom of any of the elements listed in the table? Which element has 14 protons in the nuclei of its atoms? Explain how you can determine the number of electrons surrounding the nucleus of an atom of any of the elements listed in the table. Which element has 19 electrons surrounding the nuclei of its atoms? Explain how you can determine the number of neutrons in the nucleus of an atom of any of the elements listed in the table. Which element doesn’t have a neutron in the nuclei of its atoms? How many neutrons are present in the nucleus of an iron atom? How many protons, neutrons, and electrons are present in and surrounding the nucleus of a chlorine atom?
Silicon has 14 protons Potassium has 19 electrons The neutrons are equal to the mass number minus the atomic number. Or the big number minus the small number on the periodic table. hydrogen 1 does not have a neutron.
iron =56 -26 for 30 neutrons in the nucleus
Chlorine 17 protons and 17 electrons. 18 or 19 neutrons on average.
1. From the atomic number, the number of protons in an atom’s nucleus.
2. Silicon
3. You can find this from the atomic number. An atom has no overall charge, so it must have an equal number of positive protons and negative electrons. Therefore, the number of electrons surrounding the nucleus must equal the number of protons found in the nucleus, which is the atomic number.
4. Potassium
5. The mass number of an atom of an element is the combined number of protons and neutrons. So, if you subtract the number of protons—equal to the atomic number—from an atom’s mass number, the result is the number of neutrons present in the nucleus.
I belive the answer is A but the image quality is hard to tell.
Explanation:
As pressure increases the higher the melting point of rock becomes making it harder to melt, thats why molten rocks brought to the surface melt because of the change in pressure.
It means the waves collides and constructive interference occurred.
<h3>Explanation:</h3>
If the two waves coming from the opposite direction collide with each other, there are two way of their interference.
Constructive interference: An interference which results in the increase in energy. And it is when crust of a wave comes on the crust of second wave.
Destructive interference: An interference which results in decrease in energy of the resulting wave and colliding waves cancel the result of each other.
Hence in experiment there will be constructive interference.
The solubility product of a solid is the amount of solid dissociates into its respective ions in the solution. Thus more the value of the Ksp, the more is the salt soluble in the solvent.
So, Given that:-
The salt having highest value of Ksp is AgCN. So, it is most soluble.
Radioactive dating is a method of dating rocks and minerals using radioactive isotopes. This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks. Over 300 naturally-occurring isotopes are known.
