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.
Is aluminum 12 or 14 protons?
A quick looks in the periodic table will show that aluminium has an atomic number equal to 13 . This means that any atom that is an isotope of aluminium will have 13 protons in its nucleus.
Does aluminum have 13 protons?
The number of protons in Aluminium is 13. The 27 means the atomic mass is 27 . The number of protons plus the number of neutrons is 27.
Does aluminum have 12 protons?
Chapter 2 Section 5: Atomic Numbers and Mass Numbers 1. Aluminum has 13 protons, 13 electrons, and 14 neutrons.
Is aluminum a proton neutron or electron?
Summary

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.
What has an atomic number 13?
Al Aluminum The Elements, sorted by Atomic Number
| Atomic Number | Symbol | Name |
|---|---|---|
| 13 | Al | Aluminum |
| 14 | Si | Silicon |
| 15 | P | Phosphorus |
| 16 | S | Sulfur |
What has 14 protons in the nucleus?
silicon For example, silicon has 14 protons and 14 neutrons. Its atomic number is 14 and its atomic mass is 28.
What is electron and proton?
Electrons are a type of subatomic particle with a negative charge. 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).
How many neutrons does Al?
Aluminum has 13 protons 13 electrons and 14 neutrons.
How many electrons does Al?
thirteen electrons Electron Configuration of Aluminum To find the electron configuration of an atom, you first need to know the number of electrons that it has. Since aluminum's atomic number is thirteen, it has thirteen electrons.
What has 16 protons and 18 neutrons?
So, if there are 16 protons, the element must be sulfur. The mass number for this isotope is 34 – there are 16 protons and 18 neutrons.
What has 17 protons and 18 neutrons?
Answer and Explanation: Chlorine-35 has 17 protons and 18 neutrons.
What element is atomic number 14?
Silicon Silicon – Element information, properties and uses | Periodic Table.
What element is ci2?
Chlorine Chlorine is a chemical element with the symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. Chlorine is a yellow-green gas at room temperature….Chlorine.

What has 14 protons and neutrons?
silicon For example, silicon has 14 protons and 14 neutrons. Its atomic number is 14 and its atomic mass is 28.
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.
How do you find number of protons?
The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules.
- 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 electron number?
Finding the Number of Electrons The number of electrons in an atom is equal to the atomic number of an element, for neutrally charged species. This means the number of electrons and the number of protons in an element are equal. Therefore, the number of electrons in oxygen is 8.
What is the electron of aluminum?
thirteen electrons To find the electron configuration of an atom, you first need to know the number of electrons that it has. Since aluminum's atomic number is thirteen, it has thirteen electrons.
Why does aluminum have 10 electrons?
The valence shell of aluminum has three electrons, and per the octet rule, these three electrons are lost resulting in just 10 electrons and 13 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 22 neutrons?
argon Since, a neutral atom of argon also has 22 Neutrons.
What element has a proton of 17?
chlorine atom Untitled Document. Although every atom has equal numbers of protons and electrons, the number of neutrons can vary. For example, every chlorine atom has 17 electrons and 17 protons; its atomic number is 17.
Which element is atomic number 13?
Aluminium Aluminium – Element information, properties and uses | Periodic Table.
What does Cl2 stand for?
Chlorine Chlorine | Cl2 – PubChem.
What is chlorine’s number of neutrons?
Chlorine has an atomic number of 17 and an atomic mass of 35.45, meaning that an atom of chlorine consists of 17 protons, 17 electrons, and 18 neutrons.
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 is the element with 12 protons?
magnesium On the periodic table of elements, magnesium is represented by the symbol Mg. It has an atomic number of 12 because it has 12 protons in its nucleus.
What has 7 protons and neutrons?
Nitrogen Nitrogen is an atom that has 7 protons, 7 neutrons, and 7 electrons. The neutrons and protons are all stuck together in the middle of the atom and are called the nucleus.
