What two elements have 14 neutrons?
Silicon has 14 protons and 14 neutrons. Silicon’s atomic number is 14, which tells us that it has 14 protons.
What is the symbol of an element with 14 neutron?
Silicon – Si
#14 – Silicon – Si.
What element contains 14 neutrons and 13 protons?
Aluminum’s
The isotope Al-27 has 13 protons and 14 neutrons. Aluminum’s average atomic mass is 26.981539 AMU.
What isotope has 14 protons and 15 neutrons?
mass number = 29 Therefore the isotope with 14 protons and 15 neutrons is Silicon-29.
What is the atomic mass of an atom with 14 protons 17 neutrons and 14 electrons?
For example, silicon has 14 protons and 14 neutrons. Its atomic number is 14 and its atomic mass is 28. The most common isotope of uranium has 92 protons and 146 neutrons. Its atomic number is 92 and its atomic mass is 238 (92 + 146)….2.1 Electrons, Protons, Neutrons, and Atoms.
| Elementary Particle | Charge | Mass |
|---|---|---|
| Neutron | 0 | 1 |
| Electron | −1 | ~0 |
Which element has an atomic number of 14?

Silicon is a chemical element with symbol Si and atomic number 14.
What isotope has 14 protons 15 electrons?
silicon
The element with an atomic number of 14 is silicon (Si).
What is the nucleon number of an atom with 14 neutrons and 13 electrons?
| Name | Aluminum |
|---|---|
| Number of Protons | 13 |
| Number of Neutrons | 14 |
| Number of Electrons | 13 |

What is the atomic number of an element with 13 protons 14 neutrons and 13 electrons and a mass number of 27?
Therefore, for an atom of aluminum, there are 13 electrons inside it. So we’ve demonstrated that for an aluminum atom which has the atomic number of 13 and has a mass number of 27, there are 13 protons, 14 neutrons, and 13 electrons.
How many protons and neutrons does carbon 14 have?
six protons
For example, carbon-14 is a radioactive isotope of carbon that has six protons and eight neutrons in its nucleus. We call it carbon-14 because the total number of protons and neutrons in the nucleus, also known as the mass number, adds up to 14 (6+8=14).
What is the mass number of a certain element if the proton is 15 and the neutron is 14?
How to find the neutrons in the periodic table?
Locate the element on the periodic table. For this example,we’ll look at osmium (Os),which is in the sixth row down.
Are the periodic table of elements arranged by neutrons?
The elements of the periodic table are arranged into rows and columns , called periods and groups, respectively. Every element on the periodic table contains certain numbers of protons, neutrons, and electrons that define their chemical properties.
What are the unknown elements in the periodic table?
Moseley also noticed three gaps in his table of x-ray frequencies, so he predicted the existence of three unknown elements: technetium ( Z = 43), discovered in 1937; promethium ( Z = 61), discovered in 1945; and rhenium ( Z = 75), discovered in 1925.
How are protons represented in the periodic table?
In the periodic table the elements are arranged in columns and rows according to increasing atomic numberatomic number, often represented by the symbol Z, the number of protons in the nucleus of an atom , as well as the number of electrons in the neutral atom.
