How many protons and electrons are in silicon?
The average silicon atom has fourteen protons, fourteen electrons, and most have 14 neutrons. This is a digram of a silicon atom. This shows the 14 protons in the nucleus and where the 14 electrons are located. The four electron, highlighted in green, that are located in the outer ring are the valence electrons.
How many protons and neutrons are there in silicon?
The atomic number is equal to the number of protons in the atom, therefore silicon has 14 protons. In a neutral species, the number of protons equals the number of electrons so silicon also has 14 electrons. The mass number is the number of protons plus neutrons, therefore 28 – 14 protons equal 14 neutrons.
How many neutrons are in silicone?
14 Neutrons The Mass number is equal to the number of Protons plus the number of Neutrons in an atom, so by subtracting the Atomic number from the Mass number we can determine that there are 28 – 14 = 14 Neutrons in Silicon.

What element has 18 protons and 22 neutrons?
Argon So, the atomic number is also (18), and the element with atomic number (18) is Argon with the symbol (Ar). Now we need to find the mass number of Argon. Since, a neutral atom of argon also has 22 Neutrons. So, it is clear that this is not an isotope but a neutral atom of Argon.
What atom has 15 protons and 16 neutrons?
phosphorus A nucleus of stable phosphorus has 15 protons and 16 neutrons.
How do you find protons electrons and neutrons?
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
What are electrons protons and neutrons?
Electron, proton, neutron are subatomic particles which build the atom. The atom consists of a central nucleus containing neutron and proton. Electrons revolve around the nucleus. Electrons are negatively charged, proton is positively charged and neutron is neutral. Chemistry.

| Neutron | 0 | 1 |
| Electron | −1 | ~0 |
What element has 16 protons and 18 neutrons?
A quick look in the periodic table will reveal that you're dealing with an atom of sulfur, S .
How do you find number of protons?
The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules.
- The number of protons in the nucleus of the atom is equal to the atomic number (Z).
- The number of electrons in a neutral atom is equal to the number of protons.
How many protons and neutrons does each element 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)….2.1 Electrons, Protons, Neutrons, and Atoms.

How many protons does SI 32 have?
How many protons and neutrons does silicon 32 have? Silicon has 14 protons 14 neutrons and 14 electrons.
What has 16 protons and electrons?
If a sulfur atom has 16 protons, 16 electrons, and 16 neutrons, what is its atomic mass?
What element has 22 neutrons?
argon Since, a neutral atom of argon also has 22 Neutrons.
What has 12 protons and 12 neutrons?
Magnesium atoms So you might account for this isotope problem by saying that about 79% of all Magnesium atoms have 12 neutrons, 12 protons, and 12 electrons.
What has 18 protons and 20 neutrons?
You gots Z=18 , the atomic number, where Z is the number of nuclear protons. The number of protons defines the element….and thus we got calcium…. ….and with 20 neutrons we got the 38Ca isotope….the which is rather short-lived….
What element has 17 protons and 18 neutrons?
chlorine atom Every chlorine atom has 17 protons in its nucleus. Not all atoms of chlorine have the same number of neutrons, however. Some atoms of chlorine have 18 neutrons in their nuclei.
Are protons and electrons equal?
The number of electrons on a neutral atom is equal to the number of protons in the nucleus of the atom.
What is proton and neutron?
Protons are a type of subatomic particle with a positive charge. Protons are bound together in an atom's nucleus as a result of the strong nuclear force. Neutrons are a type of subatomic particle with no charge (they are neutral).
How many protons are in an element?
The number of protons in an atom is equal to the atomic number of the element. For example, let's use oxygen. According to the periodic table, oxygen has the atomic number eight. The atomic number is located above the element's symbol.
