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.
How many electrons sodium have?
So… for the element of SODIUM, you already know that the atomic number tells you the number of electrons. That means there are 11 electrons in a sodium atom.
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.
How do u find neutrons?
For all atoms with no charge, the number of electrons is equal to the number of protons. The mass number, 40, is the sum of the protons and the neutrons. To find the number of neutrons, subtract the number of protons from the mass number. number of neutrons=40−19=21.
Why does sodium have 11 protons and 12 neutrons?
If it is a sodium atom, then Z = 11 by definition. If there are 11 protons, THERE MUST be 11 electrons orbiting around the atom, because the element here is NEUTRAL. If it is a 23Na nuclide, there must be 12 neutrons in the nucleus.
How many protons does sodium contain?
The element Sodium has an atomic number of 11 and an average atomic mass of 22.98 which makes the mass number 23. An atomic number of 11 means this atom will have 11 protons. A mass number of 23 means 23 – 11 this atom will have 12 neutrons.
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.
Why does sodium have 11 electrons?
The atomic number of an element tells you how many protons that the element has. This is written at the bottom left hand side of the symbol. Since atoms are neutral, we know then that sodium atoms must also have 11 negative electrons to cancel the charge from 11 positive protons.
What has 12 protons and 25 neutrons?
Magnesium, in its elemental form, has 12 protons and 12 electrons. The neutrons are a different matter. Magesium's average atomic mass is 24.305 atomic mass units, but no magnesium atom has exactly this mass.
How do you find protons neutrons and electrons?
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
Does sodium have 11 or 12 neutrons?
Since sodium has 11 protons, the number of neutrons must be 23 – 11 = 12 neutrons.
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 has 20 neutrons and protons?
The mass number of calcium which has 20 protons and 20 neutrons is. The mass number of calcium which has 20 protons and 20 neutrons is.
What atom has 11 protons 11 electrons and 12 neutrons?
sodium atom Let's look at a sodium atom. It has 11 protons and 12 neutrons in its nucleus, and 11 electrons outside the nucleus. Sodium is one of several atoms that easily donates an electron.
How many protons and electrons are in each atom?
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. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.
What has 11 protons and neutrons?
sodium Since sodium has 11 protons, the number of neutrons must be 23 – 11 = 12 neutrons.
What 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 atom has 16 neutrons?
if you look at the periodic table, phosphorus has 15 electrons and protons, and 16 neutrons.
How do you find the protons neutrons and electrons?
