Silicon is a non metal element. Atomic Mass number of it is 28.
What else can I help you with?
What is the mass number of an element that consists of 6 protons 6 electrons and 8 neutrons?
Just add the protons and the neutrons. The answer is 14.
How do you work out how many electrons protons and neutrons an atom has?
if it is a discovered element, look up its atomic number. that is a count of the number of protons in an atom of that element. the number of protons can also be determined by the magnetic charge with no electrons.
Which particle is used to identify isotopes of an element?
Isotopes of an element are identified by the mass number, which is the sum of protons and neutrons in the nucleus of an atom. This isotope notation is written as element symbol followed by the mass number. For example, carbon-12 and carbon-14 are two isotopes of carbon with mass numbers 12 and 14, respectively.
What element contains 11 protons 11 electrons and 14 neutrons?
The element with 11 protons and 11 electrons is sodium (Na), which has an atomic number of 11. The presence of 14 neutrons indicates that this is an isotope of sodium, specifically sodium-25. Isotopes differ in the number of neutrons, affecting their mass but not their chemical properties.
How do you determine neutrons?
When inspecting the Periodic Table, you will find two number against each element. The smaller number is the Atomic Number and also the number of protons in the element. The larger number is the Atomic Mass , which is the total of all the protons and neutrons in that element. Hence to find the number of neutrons in an element. Subtract Atomic Mass from Atomic Number.= number of 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 is the mass number of an element that has 14 electrons and 15 neutrons?
The mass number is equal to the sum of protons and neutrons in an atom. Since the element has 14 electrons and 15 neutrons, it must have 15 protons (atomic number is equal to number of protons). So, the mass number would be 15 + 15 = 30.
Atomic number of an element is 6 and atomic weight is 14 it has --- number of protons and --- number of electrons?
The isotope carbon 14: Atomic number = number of protons = number of electrons = 6 Atomic mass: 14,003241
What is the mass number of an element that consists of 6 protons 6 electrons and 8 neutrons?
Just add the protons and the neutrons. The answer is 14.
How many valence electrons would an element with an atomic number of 14 have?
An element with an atomic number of 14, such as silicon, would have 4 valence electrons. Valence electrons are the electrons in the outermost energy level of an atom, which corresponds to the group number of the element on the periodic table.
How do you work out how many electrons protons and neutrons an atom has?
if it is a discovered element, look up its atomic number. that is a count of the number of protons in an atom of that element. the number of protons can also be determined by the magnetic charge with no electrons.
How many protons will notrogen have if the mass number is 14?
Nitrogen is a non metal element. Mass number of it is 14.
How many protons neutrons and electrons are in aluminum?
The number of protons for any element is the atomic number. The number of electrons is equal to the number of electrons. To find the number of nuetrons you must subtract the atomic number from the mass number mass number-atomic number= number of nuetrons protons=electron the number of protons in the element aluminum is 13. The number of electrons is 13.

An atom of aluminum (Al) has an atomic number of 13 and a mass number of 27. How many neutrons does it have?
an element always has as many electrons as protons...... the Atomic Number equals the number of protons. So if your atomic number is 13......you have thirteen protons.....and therefore 13 electrons
A neutral atom has a mass number of 32 In what group does this element belong?
A neutral atom that is not an isotope with an atomic mass of 32 is sulfur. Sulfur belongs to group XVI.
