What are the subatomic particles of atom?
as far as i know aluminum is a molecule not an atom. The aluminum atom has a valence of 3, what its chemical structure is depends on what it combines with.
How many neutrons are in carbon 13?
well the mass number is actually 12. because the ATOMIC MASS is 12.011. and to find the mass number you must round the atomic mass to the nearest WHOLE NUMBER. 12.011 rrounded to its nearest whole number would be 12. and to find the number of neutrons you must subtract the ATOMIC NUMBER (which is 6) from its mass number. 12-6=6. so carbon has 6 neutrons. carbon also has 6 protons, as well as 6 electrons.
What are the protons neutrons and electrons for magnesium atom?
Atomic # : 12 Mass Number : 24 # of Protons : 12 #of Neutrons : 12 # of Electrons : 12
If an atomic number of an element is 6 and its mass is 14 how many neutrons are contained in the nucleus?
The atomic number always corresponds with the number of protons in the atom, therefore, since the atomic number is six, there are six protons in the atom.Because the atom has no specified charge, you can assume that the charge is zero and that there are the same number of electrons as protons, also six.The mass of an atom is the number of protons plus the number of neutrons because electrons are tiny. So, you know there is a mass of 14, subtract six from the protons and you get the neutrons (14-6protons=8neutrons)Hope this helped!!
How many protons does an atom have with a mass number of 43 and 21 electrons?
The atomic no. in this case 22, is equal to the no of protons and also electrons. So it has 22 protons and 22 electrons. The mass no. is equal to the no. of protons plus the no. of neutrons. So it has 22 protons and 26 neutrons. The metal with atomic no. 22 on the periodic table is titanium.
An atom has 13 protons and an atomic mass of 27 How many neutrons does this atom have?
The atom in question has 13 protons, so is atomic number 13, which is Aluminium. Assuming that all of the atom's mass is formed from the protons and neutrons, and each of these have atomic mass 1, the number of neutrons is 27 - 13 = 14 neutrons. Almost all Aluminium is of this isotope.
What is the mass of an atom that has 10 protons 13 neutrons 10 electrons?
The mass number of this atom is 23, the sum of the number of protons and neutrons.
An atom has 14 protons and 13 neutrons what it its atomic mass?
27 add protons and neutrons
How can you find the number of neutrons that are in the nucleus of an atom?
Aluminum is 13 because that is the atomic number (the number of protons). The atomic mass number is the number of protons and neutrons in an atom. In this, you just subtract the number of protons from the mass number. If Aluminum (Al), #13, has a mass number of 27, then it has 14 neutrons. Pretty simple.
How many neutrons does an atom with a mass of 13 and 9 protons?
the atomic mass of carbon 13 is 13 lt has six protons how many neutrons does this isotope
How many protons are in an atom with atomic mass of 6 and mass number of 13?
The atomic number is equal to the number of protons in the nucleus. The mass number is equal to the total number of nucleons (both protons and neutrons). Therefore, there are 13 protons and neutrons, 6 of which are protons, leaving the remaining 7 to be neutrons. In short, 6 protons, 7 neutrons. You're referring to carbon-13, an uncommon isotope of carbon. Sharondenadel The atomic number is equal to the number of protons in the nucleus.

How many electron neutron and protrons are in an aluminum atom?
No. of electrons = No. of protons = Atomic No. =13 No. of neutrons=Atomic mass - No.of protons=27-13=14
An atom has 11 protons 13 neutrons and 11 electrons What are possible isotopes of this atom?
An atom with 11 protons, 12 neutrons, and 11 electrons. B. An atom with 11 protons, 10 neutrons, and 11 electrons.An atom with 11 protons, 12 neutrons, and 11 electrons.
What is the atomic mass of a atom that has 6 neutron 6 protons and 6 electron?
Number of protons = atomic number = 6 atomic units Number of protons + neutrons = mass number = 13 atomic units
What are the number of protons and neutrons in aluminum?
There are 13 protons and 14 neutrons in the nucleus of an aluminum atom. The number of protons is the same as the atomic number and the number of neutrons is just the mass number - atomic number. In a stable atom anyway, there's different isotopes which is where there is a different number of neutrons, but if it doesn't specify then this is what it is.
How many neutrons are found in an atom of aluminum-27?
Number of neutrons = Mass number - Number of protons = 26 - 12 = 14 neutrons
What are the subatomic particles of atom?
as far as i know aluminum is a molecule not an atom. The aluminum atom has a valence of 3, what its chemical structure is depends on what it combines with.
