What element contains 14 protons and 15 neutrons?
The 14 protons means it has the atomic number 14, and from the periodic table you can see that it is silicon, Si. The 15 neutrons added to the 14 protons means it has a mass number of 29, and is an isotope of silicon called silicon-29.
What have 14 Protons?
To figure this out, all you need to do is look at a periodic table. On the periodic table, locate the element whose atomic number is 14 and you have your answer. It turns out that that element is silicon.
Which group is the element carbon in on the periodic table?
group 14
What element contains 14 protons?
The element that contains 14 protons in its atoms has the atomic number 14. On the Periodic Table, this element is silicon, Si.
What is the element Si on the periodic table?
The element Silicon is represented on the periodic table by the symbol Si.
How many neutrons does an atom of carbon-14 contain?
The position of Carbon on the periodic table tells you how many protons carbon has in its nucleus. The number after it tells you the total number of protons and neutrons. You can take the number after it and subtract its number on the periodic table and get the number of neutrons. For example: Helium is the second element in the periodic table. Helium 3 has two protons and one neutron. Helium 4 has 2 protons and 2 neutrons. Since it is element number 2 it has two protons. Now try that with carbon.
What are the number of protons and neutrons in the following Mg with atomic mass of 26?
Mg has 12 protons since it is element number 12 on the periodic table. To calculate the number of neutrons, subtract the atomic number (12 protons) from the atomic mass (26), which gives 14 neutrons in this case.
Where is Carbon the element located?
group 14, period 2 on the periodic table
Where do you find silicon equals element?
Look on the periodic table of elements. You will find silicon as element 14.
Where is carbon located on the periodic table?
Carbon is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. It belongs to group 14 of the periodic table. Carbon makes up only about 0.025 percent of Earth's crust. So, yes it is.
Is silicon a group 4 element?
No. In the modern periodic table, silicon (element 14) is a metalloid in group 14.Group 14 was previously known as "group IV" (A or B).
Which element on the periodic table has 14 protons?
Magnesium2+ because it donated 2 electrons
