Where can protons and neutrons be found?
the nucleus
Protons and neutrons are heavier than electrons and reside in the nucleus at the center of the atom.
What is the protons and electrons of Na+?
There are 10 electrons present in Na+. The atom of sodium has 11 electrons, 11 protons along with 12 neutrons, but Na+ contains one less electron, 11 protons along with 12 neutrons, as the ion has lost 1 electron.
How do you find the protons neutrons and electrons of an ion?
The proton number is the atomic number of the element, while the electron number is the atomic number minus the charge. A negatively-charged ion or anion has more electrons than protons. Again, the number of protons is the atomic number. The number of electrons is the atomic number added to the charge.
How do you find the number of protons neutrons and electrons in sodium?
So sodium has 11 protons and 11 electrons. The mass number is 23. The number of neutrons = mass number – atomic number. The number of neutrons = 23 – 11 = 12.
Where are electrons found?
outside the nucleus
Unlike protons and neutrons, which are located inside the nucleus at the center of the atom, electrons are found outside the nucleus. Because opposite electric charges attract each other, negative electrons are attracted to the positive nucleus.
Where are protons located in the periodic table?
The atomic number (number at the top) is the amount of protons and the amount of electrons. So if an element has an atomic number of 5, you know that it has 5 protons and 5 electrons. The atomic mass (number at the bottom) is the amount of protons and neutrons added together.
Why is sodium not found uncombined?
Chemical Properties: Sodium is a very reactive element and is never found in the uncombined state in nature. Sodium has one electron in its outer energy level that is the source of its chemical reactivity. Sodium metal reacts spontaneously with water to give sodium hydroxide and hydrogen gas.
Where are protons located on the periodic table?
Where are leptons found in an atom?
We have seen that the electron has an anti-particle – the positron. Like the electron, this is a fundamental particle and is a member of the family of leptons. They are both found in normal matter and are known as first generation leptons….

What is the number of protons electrons and neutrons in sodium?
The element sodium has 12 neutrons, 11 electrons and 11 protons. The number of electrons and protons come from the element’s atomic number, which is same 11. The number of neutrons can be found by subtraction of the atomic number from sodium’s atomic mass of twenty three.
How do you find the number of protons electrons and neutrons?
The number of electrons and protons come from the element’s atomic number, which is same 11. The number of neutrons can be found by subtraction of the atomic number from sodium’s atomic mass of twenty three. Secondly, how many protons electrons and neutrons are in a given element?
How many protons neutrons and electrons are in 23 11?
So there are 23 – 11 = 12 neutrons. Moreover, how many protons neutrons and electrons does sodium have? The element sodium has 12 neutrons, 11 electrons and 11 protons. The number of electrons and protons come from the element’s atomic number, which is same 11.
What is the electron configuration of the ionic compound sodium?
Electron configuration of Sodium is [Ne] 3s1. Possible oxidation states are -1; +1 . Sodium atoms have 11 electrons, one more than the stable configuration of the noble gas neon.
