If a silicon atom contains 16 neutrons what is its mass number?
The mass number of an atom is the sum of its protons and neutrons. In this case, if a silicon atom contains 14 protons (since it is a silicon atom) and 16 neutrons, the mass number would be 14 + 16 = 30.
How many protons neutrons and electrons does si-28 have?
A silicon-28 atom has 14 protons, 14 neutrons, and 14 electrons. The number of protons determines the element (silicon in this case), the sum of protons and neutrons gives the atomic mass of the isotope (28 in this case), and the number of electrons balances the charge to make the atom electrically neutral.
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 has 14 neutrons?
Aluminium with atomic number 13 ie 13 protons has 14 neutrons within the nucleus. So its mass number is 27. Silicon too with atomic number 14 has 14 neutrons within. Why not? Even phosphorous with atomic number 15 has 14 neutrons. So it is an isotope that too radio active isotope. So it is very important to know about the number of protons to identify the element. But number of neutrons do differ leading to the formation of isotopes.
How many protons neutrons and electrons does silicon-30 have?
There are 14 protons and 16 neutrons in 30Si and the atom is a stable isotope of silicon.
The number of neutrons in the nucleus of a silicon atom are?
A silicon atom typically has 14 neutrons in its nucleus. This number is calculated by subtracting the atomic number (14) from the mass number (28) of silicon.
What is silicon mass number?
The mass number of silicon is 28. It is calculated by adding the number of protons and neutrons in the nucleus of a silicon atom. Silicon has 14 protons and 14 neutrons, giving it a mass number of 28.
If a silicon atom contains 16 neutrons what is its mass number?
The mass number of an atom is the sum of its protons and neutrons. In this case, if a silicon atom contains 14 protons (since it is a silicon atom) and 16 neutrons, the mass number would be 14 + 16 = 30.
What is the subatomic particle os a silicon?
Silicon has 14 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a silicon isotope = Mass number - 14
How many protrons and neutrons does silicon have in the nucleus?
How many protrons and neutrons does silicon have in the nucleus?
If an isotope of silicon has 15 neutrons what is its mass number?
The mass number of an isotope is the sum of its protons and neutrons. Since silicon has 14 protons, the isotope with 15 neutrons would have a mass number of 14 (protons) + 15 (neutrons) = 29.
How many neutrons does silicon 27 have?
Silicon-27 has 14 protons (since it is silicon) and 13 neutrons, as the atomic number (proton number) minus the mass number (proton number + neutron number) gives the number of neutrons. In this case, 27 - 14 = 13 neutrons.
How many protons and neutrons and electrons are there in a neutral atom of silicon-28?
A neutral atom of Silicon-27 contains 14 protons, just like any atom of Silicon (Si). Silicon has an atomic number of 14. The most abundant form of Si is Silicon-28, which has 14 neutrons. Silicon-27 has 13 neutrons.
How many protons neutrons and electrons does si-28 have?
A silicon-28 atom has 14 protons, 14 neutrons, and 14 electrons. The number of protons determines the element (silicon in this case), the sum of protons and neutrons gives the atomic mass of the isotope (28 in this case), and the number of electrons balances the charge to make the atom electrically neutral.
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.
How many neutrons are in a silicon atom with an atomic mass of 28?
There are 14 neutrons.Atomic Mass is the total amount of neutrons and protons that are contained within an atom's nucleus.So, if you are given the atomic mass, proton count, neutron count, or electron count, then you can find out the approximate any of those values algebraically.And remember that atomic mass has decimals since it is the average of all the element's isotopes.
There are three isotopes of silicon silicon-28 silicon-29 and silicon-30 what are the same and which are different among the atoms of these isotopes?
The atoms of all three isotopes have the same number of protons (14) and electrons, but differ in the number of neutrons: silicon-28 has 14 neutrons, silicon-29 has 15 neutrons, and silicon-30 has 16 neutrons. This variation in neutron number gives each isotope a different atomic mass.
