What two elements have 14 neutrons?
Answer and Explanation: Silicon has 14 protons and 14 neutrons. Silicon’s atomic number is 14, which tells us that it has 14 protons.
What is a metal with 14 neutrons?
SILICON – I am the 2nd most abundant element in the Earth’s crust and have 14 neutrons.
Does nitrogen have 14 neutrons?
Therefore it is neutral. Therefore Nitrogen-14 has 7 protons, 7 neutrons, and 7 electrons.
How many neutrons are in carbon-14?
eight neutrons
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 isotope of silicon has 14 neutrons?
And Z defines the identity of the atom; if Z=14 , we gots silicon…….. Because the element may contain more or less NEUTRONS than Z , where neutrons are massive, neutrally charged, nuclear particles, the isotope is 28Si , about 92.2\% abundant.
What isotope has 14 protons and 15 neutrons?
mass number = 29 Therefore the isotope with 14 protons and 15 neutrons is Silicon-29.
Which has a greater atomic number carbon 12 or carbon 14?
The number given after the atom name indicates the number of protons plus neutrons in an atom or ion. Atoms of both isotopes of carbon contain 6 protons. Atoms of carbon-12 have 6 neutrons, while atoms of carbon-14 contain 8 neutrons. Carbon-12 is lighter than carbon-14.
What element has a mass of 14?
Silicon
The elements of the periodic table sorted by atomic mass
| Atomic Mass | Name chemical element | number |
|---|---|---|
| 24.305 | Magnesium | 12 |
| 26.9815 | Aluminum | 13 |
| 28.0855 | Silicon | 14 |
| 30.9738 | Phosphorus | 15 |
Which isotope has a mass number of 14 and 8 neutrons?
carbon-14
A: Carbon atoms with 8 neutrons have an atomic mass of 14 (6 protons + 8 neutrons = 14), so this isotope of carbon is named carbon-14.
How many electrons does C 14 have?
six electrons
Neutral carbon-14 contains six protons, eight neutrons, and six electrons; its mass number is 14 (six protons plus eight neutrons).
What element has 15 neutrons and 14 protons?
Answer and Explanation: Silicon has 14 protons and 14 neutrons. Silicon’s atomic number is 14, which tells us that it has 14 protons. It has an atomic mass of 28. Because atomic mass is calculated by adding together the number of protons and neutrons in an atom of the element, this tells us that silicon must have 14 neutrons as well.
How to determine neutrons in an element?
The number of neutrons can be found simply by identifying the atomic mass (found at the bottom of the element on the periodic table) and the atomic number. Subtract the atomic number from the atomic mass. Remember that the given atomic mass has to be rounded off to the nearest whole number before any further calculations.
What element has 14 electrons?
Explanation: Silicon is an element with 14 protons, and so as a neutral element, it will have 14 electrons. Have a look here: However, if it was an ion, it could be any other element, such as H13−, if that were to exist…, since the atomic/proton number determines the element’s identity, not the electron number.
What do elements have 16 neutrons?
Isotopes are named for their mass numbers. So, this element has 15 protons (atomic number), 15 electrons, and 16 neutrons (mass number minus atomic number). This isotope is phosphorus-31, which has atomic number 15. Click to see full answer.
