How many protons electrons and neutrons does SI have?
The average silicon atom has fourteen protons, fourteen electrons, and most have 14 neutrons.
How many protons are in silicon as an ion?
14 protons The atomic number is equal to the number of protons in the atom, therefore silicon has 14 protons.
How many protons neutrons and electrons are in Si mass number 28?
Silicon-28 is composed of 14 protons, 14 neutrons, and 14 electrons.
How many neutrons do SI have?
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.
How many electrons does SI contain?
14 electrons Silicon has a total of 14 electrons. It has 2 electrons in the first shell, 8 electrons in the second shell and 4 electrons in the third shell.
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.

How do you find protons?
Locate the element's atomic number. The atomic number is located above the element symbol, in the upper left-hand corner of the square. The atomic number will tell you how many protons make up a single atom of an element. For example, boron (B) has an atomic number of 5, therefore it has 5 protons.
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 16 protons and 18 electrons and 18 neutrons?
A quick look in the periodic table will reveal that you're dealing with an atom of sulfur, S .
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.

What is in a proton?
Protons are composed of two up quarks of charge + 23e and one down quark of charge − 13e. The rest masses of quarks contribute only about 1% of a proton's mass.
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).
What element contains 7 protons?
Correct answer: Nitrogen has atomic number seven, and is the only element that can have seven protons. The given configuration is for an isotope of nitrogen. Since there are eight neutrons, this atom would be for nitrogen-15.
