What has 16 protons and neutrons?
(b) By referring to a periodic table or a table of elements, we see that sulfur (S) has an atomic number of 16. Thus, each atom or ion of sulfur must contain 16 protons. We are told that the ion also has 16 neutrons, meaning the mass number of the ion is 16 + 16 = 32.
What has 15 protons and 16 neutrons?
Explanation: if you look at the periodic table, phosphorus has 15 electrons and protons, and 16 neutrons.
How do u find neutrons?
To find the number of neutrons, subtract the number of protons from the mass number. number of neutrons=40−19=21.
How many electron does aluminum have?
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.
How many protons does aluminum ion have?
Al3+indicates an ion of aluminum having a charge of + 3. I.e., since an aluminum atom normally has 13 protons and 13 electrons, this ion has 10 electrons (-10 charge) and 13 protons (+ 13 charge) giving it a charge of + 3 (-10 + 13 = +3).
How do you find the mass number of aluminium?
- Given that, Atomic number of aluminium is 13 and its mass number is 27.
- To find, The number of electrons, protons and neutrons in its atom.
- Solution, …
- Number of neutrons = 27 – 13 = 14.
- Atomic number and atomic mass.
What is the group number of aluminum?

How many neutrons does CA have?
Atomic elements in calcium
Since a stable atom has a net charge of 0, we must have 20 electrons. The number of neutrons will be the same as the number of protons: it is also 20.
What element has 18 protons and 22 neutrons?
Given the number of protons is [18]. 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.
Why does aluminum have 13 electrons?
The electrons like to be in separate shells/orbitals. Shell number one can only hold 2 electrons, shell two can hold 8, and for the first eighteen elements shell three can hold a maximum of eight electrons. … That means there are 13 electrons in a aluminum atom.
Which element contains 47 protons?
Explanation: Numbers of Protons in Silver: The element Silver (Symbol Ag) has the Atomic Number of 47. Any atom that contains exactly 47 protons in its nucleus is an atom of silver.
How many protons does aluminum 28 have?
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.
What is the flammability of aluminum?
Aluminum remains solid at temperatures up to and including 199.4 degrees Fahrenheit (93 degrees Celsius) and will not burn except at very high temperatures. This means that aluminum is not considered flammable, nor is it considered to be combustible. It is often used for its flame retardant properties.
