What atom or isotope of an element has an atomic mass of 26 charge of 3 13 protons 13 neutrons and 10 electrons?
The number of protons identifies this element as aluminum, which has an atomic number of 13. The number of protons is an element's atomic number on the periodic table. Every element has its own unique atomic number which defines it as that element.
How many neutrons are in the nucleus of the isotopes of aluminum-25?
The atomic number of aluminum is 13, therefore there will be 13 protons.The number of neutrons equals the mass number minus the atomic number. For aluminum-25, that will be 25 - 13 = 12 neutrons.There will be 13 electrons in the neutral atom of aluminum, regardless of which isotope we are considering.
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.
How do you calculate the atom of a element?
The only way I can make this question make sense is to assume you're trying to ask "how do you calculate the number of protons and neutrons in an atom?"The name or symbol of the element will tell you the number of protons (though, if you didn't already know that, you'll likely need to look it up on a periodic table). For example, a carbon atom has 6 protons.To figure out the number of neutrons, you'll need to know the atomic mass number. This is usually given either as a superscript to the left of the element symbol, or as a number following the name or symbol of the element (often separated by a dash). For example, "carbon 13" and "C-13" both have an atomic mass number of 13. If you don't see a number ... you're in trouble (unless the element is identified as deuterium or tritium; these have 1 proton and 1 neutron, or 1 proton and 2 neutrons, respectively). You can look up the atomic mass on a periodic table, but that will be an AVERAGE value. For example, the atomic mass given for chlorine will be somewhere in the vicinity of 35.453. That's because the two most common isotopes of chlorine are chlorine-35 and chlorine-37, in about a 3 to 1 ratio. You can't identify the number of neutrons unless you know specifically which isotope is meant.Assuming you do know the atomic mass number; it's also the number of nucleons. Subtract the number of protons from the atomic mass number, and what's left over is the number of neutrons.So: carbon-13 has 6 protons (because it's carbon) and 7 neutrons (because 13-6 = 7).
How many protons does the element have in group 13 and the 3rd period?
13 protons an easy way to remember what number of protons an element has is APES. A-atomic number, P-protons, E-electrons, S-same, so the atomic number and the numbers of protons and electrons are the same number
What element has a mass number of 28 and 13 protons?
The element has 13 protons. So the element is aluminium. It has 15 neutrons (28 - 13 = 15) and the isotope is 13Al28
What is the mass of an atom with 13 protons and 14 neutrons?
26 is the atomic mass because the number of protons and neutrons together = atomic mass
What atom or isotope of an element has an atomic mass of 26 charge of 3 13 protons 13 neutrons and 10 electrons?
The number of protons identifies this element as aluminum, which has an atomic number of 13. The number of protons is an element's atomic number on the periodic table. Every element has its own unique atomic number which defines it as that element.
What is aluminums symbol?
the symbol is Al and the charge is negative 3.
What element does have 13 protons?
Aluminium, Al, has 13 protons.
How many protons will carbon have if the mass number is 13?
it is possible for a particular element to have various numbers of neutrons
How many neutrons are in the nucleus of the isotopes of aluminum-25?
The atomic number of aluminum is 13, therefore there will be 13 protons.The number of neutrons equals the mass number minus the atomic number. For aluminum-25, that will be 25 - 13 = 12 neutrons.There will be 13 electrons in the neutral atom of aluminum, regardless of which isotope we are considering.
Carbon has an atomic number of 6 how many protons and neutrons are in a nucleus of carbon 13?
12 - 6 = 6 neutrons; the number of neutrons in an isotope is always the mass number minus the atomic number.
What element has 11 protons and 13 neutrons?
Sodium, Na, is the element that has eleven protons.
Which symbol represents an atom with 13 protons 17 neutrons and 12 electrons?
There is an error in the question - this is not an element as it would have an equal number of protons and electrons. 13 protons means it is Aluminum -12 electrons would mean it was Aluminum with one positive charge - which just does not happen. 17 neutrons would mean it is a heavy isotope of Aluminum Al30 - question needs to be rechecked and corrected
What is the 12th element of the periodic table?
Aluminium is the 13th element, with an atomic number (of protons in the nucleus) of 13 and a mass number of 27 (number or neutrons + protons).
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
