How many electrons are in a sodium-23 atom?

11 electrons
The mass number is given at the top left of the elements symbol, for example, sodium has a mass number of 23. We know that the atomic number of sodium is 11. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons.

How many protons and neutrons are in an atom of NA 23?

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.

How many protons neutrons and electrons are in a neutral atom of sodium-24?

Sodium-24 is composed of 11 protons, 12 neutrons, and 11 electrons. Sodium-24 is one of the most important isotopes. It is radioactive and created from common sodium-23 by neutron bombardment.

What is the protons of sodium-23?

11
sodium-23/Protons

What do you call a sodium atom that has 10 electrons?

Ion Characteristics So now you’ve become a sodium ion. You have ten electrons. That’s the same number of electrons as neon (Ne).

What element has 18 protons and 22 neutrons?

Argon
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 is sodium 23?

Sodium, for example, has 2 isotopes. The atoms of both isotopes contain 11 protons, but sodium-23 has 12 neutrons whereas sodium-24 has 13. Sodium-23 is quite stable (for example, it is one of the elements in common salt – NaCl, sodium chloride).

Why the mass of sodium is 23?

Mass number = Total number of protons + Total number of neutrons Sodium atom has 11 protons and 12 neutrons in its nucleus. Thus, we get the atomic mass number 11 + 12 = 23.

Why is the mass number of sodium 23?

Sodium is an alkali metal that comes first in the 3rd period of the periodic table. Mass number = Total number of protons + Total number of neutrons Sodium atom has 11 protons and 12 neutrons in its nucleus. Thus, we get the atomic mass number 11 + 12 = 23.

What is a 3+ ion?

aluminum(3+) Aluminium, ion (Al3+)

What has 17 protons and 18 neutrons?

chlorine atom
Every chlorine atom has 17 protons in its nucleus. Not all atoms of chlorine have the same number of neutrons, however. Some atoms of chlorine have 18 neutrons in their nuclei.

How many neutrons are present in sodium?

There are 12 neutrons in the sodium atom . Each atom also has 11 protons and 11 electrons, giving sodium an atomic number of 11.

What element has 23 protons?

Vanadium is a chemical element with symbol V and atomic number 23. It is a hard, silvery-grey, ductile, and malleable transition metal.

Is sodium the only element with eleven protons?

The only element in group 1 with the atomic number (number of protons) 11, is Sodium . The element Sodium (Na) has 11 protons and 1 valence electron. Before the punic wars, how did the early romans take over italy?…
