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's the mass number for sillicon?
Silicon is a non metal element. Atomic mass of it is 28.
How many grams of oxygen are in 10.00x1028 molecules of silicon dioxide?
10.00 X 10^28 = 1.0 X 1^29 ( always use scientific notation in chemistry ) 1.0 X 10^29 molecules silicon dioxide (1 mole SiO2/6.022 X 10^23)(2 mole O/1 mole SiO2)(16.0 grams/ 1 mole O) = 5.3 X 10^6 grams of oxygen
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 has Atomic Number of 29?
The atomic number 29 corresponds to the element copper (Cu). Copper is a ductile metal with high thermal and electrical conductivity, often used in electrical wiring, plumbing, and other applications.
If an isotope of silicon has 15 neutrons what is the mass number?
The mass number of an isotope is the sum of its protons and neutrons. Silicon has an atomic number of 14, meaning it has 14 protons. If the isotope has 15 neutrons, the mass number would be 14 protons + 15 neutrons, which equals 29. Therefore, the mass number of the silicon isotope is 29.
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.
What element has an atomic mass of 29?
silicon
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 is the average atomic mass of the three silicon isotopes?
The average atomic mass of silicon is around 28.09 atomic mass units. This is due to the natural abundance of the three silicon isotopes: silicon-28, silicon-29, and silicon-30. Silicon-28 is the most abundant isotope at about 92.23%, followed by silicon-29 at about 4.67%, and silicon-30 at about 3.1%.
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.
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.
How many protons electrons and neutrons does Si-29 has?
Silicon-29 has 14 protons (atomic number), 14 electrons if the atom is neutral, and 15 neutrons (mass number - atomic number).
What's the mass number for sillicon?
Silicon is a non metal element. Atomic mass of it is 28.
What element has 14 electrons and a mass number of 28?
Silicon is a non metal element. Atomic mass number of it is 28.
What is the mass number is silicon?
14
Consider the silicon 29 isotope How many protons and neutrons and electrons will it have?
All silicon atoms have 14 electrons and 14 protons. That is a rule that every silicon atom must follow. On the periodic table, the number next to the atom is the number of electrons/protons in an atom (silicon is the 14th element listed on the periodic table, hence the 14 electrons and 14 protons). The number "29" is the number of protons and neutrons together. This number can change with changing isotopes. So, if every silicon atom must have 14 protons, and 29 is the number of protons and neutrons together, so the number of neutrons must be 29 minus 14. Final: 14 protons 14 electrons 15 neutrons
