Which element has the atomic number 13 and mass number 27?
An atom of aluminum has an atomic number of 13 and a mass number of 27.
How many protons are present if an atom has a mass number of 27 and atomic number of 13?
Neutrons and protons are the massive fundamental particles, which determine the mass of a given isotope. And thus for 27Al , we know that there are 14 neutrons , because if it is an aluminum nucleus it MUST have 13 protons .
What charge would an element have if it has 13 protons and 13 electrons?
Explanation: Aluminum has (by definition) 13 protons, 13 positively charged particles. Because aluminum is neutral (as is all matter), it therefore has 13 negatively charged particles, electrons.
How many electrons are there in aluminum atoms with an atomic number of 13?
Explanation: In the neutral species, and we have defined an aluminum nucleus, i.e. Zatomic number=13 , there are necessarily 13 electrons, i.e. there must be equal numbers of electrons and protons, for neutrality. Of course, we could have Al3+ , which of course has 10 electrons…..
Which element is atomic number 13?

Which element has an atomic number 13?
Aluminum is a chemical element with symbol Al and atomic number 13.
How many neutrons are present in an aluminum atom that has an atomic number of 13 and a mass number of 27?
14 neutrons
The atomic number is the number of protons in the nucleus. →27−13=14 neutrons!
Does atomic number equal protons?
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.
What is the neutrons of an element that has 13 protons 13 electrons and a mass number of 27?
Therefore, for an atom of aluminum, there are 13 electrons inside it. So we’ve demonstrated that for an aluminum atom which has the atomic number of 13 and has a mass number of 27, there are 13 protons, 14 neutrons, and 13 electrons.
What is the ion’s charge if there are 13 protons and 10 electrons?
3+
The aluminum ion has 10 electrons and 13 protons, so it has lost three electrons, and has a charge of 3+ .
What does the number 13 mean in aluminum?
Aluminum (aluminium) is the element that is atomic number 13 on the periodic table. Each atom of aluminum contains 18 protons. Aluminum atoms with fewer than 18 electrons are cations, while those with more than 18 electrons are anions. The isotope of aluminum is determined by its number of neutrons.
How many protons does aluminum atom with 13 have?
13 protons
Therefore, for an atom of aluminum, there are 13 electrons inside it. So we’ve demonstrated that for an aluminum atom which has the atomic number of 13 and has a mass number of 27, there are 13 protons, 14 neutrons, and 13 electrons.
How many protons does an atom with an atomic number 13 have?
An atomic number of 13 means the atomic nucleus has 13 protons. The number of electrons always equals the number of protons. So, this atom has 13 electrons.
What is the mass number of an atom?
The atomic mass (mass number) is the sum of the protons and neutrons in the nucleus. Mass number can vary due to the fact that the number of neutrons can vary. Isotopes are named for their mass numbers.
How many protons electrons and neutrons does an isotope of an element have?
Isotopes are named for their mass numbers. So, this element has 15 protons (atomic number), 15 electrons, and 16 neutrons (mass number minus atomic number).
How many elements are there in the periodic table by mass?
