What is the number of neutrons?

Since the vast majority of an atom’s mass is found its protons and neutrons subtracting the number of protons (i.e. the atomic number) from the atomic mass will give you the calculated number of neutrons in the atom. In our example this is: 14 (atomic mass) – 6 (number of protons) = 8 (number of neutrons).

What is the flammability of Silicon?

Silicone is not considered to be flammable. It can catch fire and burn but requires high temperatures to do so. The ignition temperature of silicone is 842 degrees Fahrenheit (450 Celsius).

What is electron configuration of Silicon?

[Ne] 3s² 3p²

How do you find the neutrons of silicon?

Does silicon have 7 electrons?

So… for the element of SILICON you already know that the atomic number tells you the number of electrons. That means there are 14 electrons in a silicon atom. Looking at the picture you can see there are two electrons in shell one eight in shell two and four in shell three.

How many neutrons does Silicon 30 have?

16 neutrons

So our atom of silicon-30 also contains 16 neutrons. Just like with the atom of carbon we’re dealing with a neutral combination of protons and electrons. So we need 14 electrons to balance out the charge of the 14 protons.

How many protons electrons and neutrons are in Silicon 29?

Silicon-29 is composed of 14 protons 15 neutrons and 14 electrons.

How do you write silicon-28?

What is proton neutron and electron?

Atoms are made of extremely tiny particles called protons neutrons and electrons. Protons and neutrons are in the center of the atom making up the nucleus. Electrons surround the nucleus. Protons have a positive charge. Electrons have a negative charge.

How is the neutron number computed?

To calculate the number of neutrons in the nucleus of an atom is simple. You take the atomic or proton number of the element and you subtract it from the element’s mass number. … In order to calculate the number of neutrons you must take its mass number (63) away from its atomic number (29) which leaves you with 46.

How do you find the neutron number?

To find the number of neutrons subtract the number of protons from the mass number. number of neutrons=40−19=21.

What is the molar mass of silicon?

Does silicon melt or burn?

While most plastics will begin to melt at high temperatures silicone does not have a melting point and remains solid until combustion occurs. At high temperatures (200-450oC) silicone rubber will slowly lose its mechanical properties over time becoming brittle.

How many nucleons does silicon have?

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).

How many electrons does silicon 3 have?

Silicon is made up of 14 electrons 14 protons and (in most cases) 14 neutrons. In its ground state silicon has two electrons at the energy level n = 1 eight at the energy level n = 2 and four at the energy level n = 3 as shown in the energy diagram on the left.

What has 15 protons and 16 neutrons?


A nucleus of stable phosphorus has 15 protons and 16 neutrons.

What is the mass of silicon-30?


silicon-30 atom (CHEBI:37976) The stable isotope of silicon with relative atomic mass 29.9737702.

How many covalent bonds can silicon 28 form?

This means that there are four unpaired electrons in its outer energy level (comparable to carbon). Based on this fact you can conclude that silicon like carbon could form four covalent bonds.

What is the mass number of a silicon atom with 16 neutrons in its nucleus?

16 neutrons. Silicon-30 is an isotope of Silicon. It has a mass number of 30.

Why does silicon have 15 neutrons?

Explanation: If it’s 29Si the superscript refers to the number of massive nuclear particles: 14 protons obviously (why?) and necessarily 15 neutrons i.e. isotopic mass = 14+15 to make up the isotopic mass.

What is the mass number of silicon if it has 15 neutrons?


However 5% of silicon atoms have 15 neutrons and another 3% have 16 neutrons giving them atomic masses of 29 and 30 respectively. The atomic mass of silicon is said to be therefore 28.086 when one factors in the masses and relative abundances of different isotopes of silicon.

What is the difference between 28 Si and 29 Si?

Explanation: The abundance of Si-28 is 92.23%. Si-29 is 4.68% and Si-30 is 3.09%. Because most Si atoms have a mass of 28 amu the average mass of all silicon atoms is very close to 28.
