2009-12-05 · Na+ has 11 protons, 10 electrons and 12 neutrons and Cl- has 17 protons, 18 electrons and 18 neutrons.

Hydrogen has 1 proton, 0 neutron and 1 electron. 2. Helium has 2 protons, 2 neutrons and 2 electrons. The Mass Number of an element is equal to the protons added to the neutrons. The element Sodium has an atomic number of 11 and an average atomic mass of 22.98 which makes the mass number 23. Therefore . An atomic number of 11 means this atom will have 11 protons.

Magnesium naturally occurs in three stable isotopes, 24Mg, 25Mg, and 26Mg. Magnesium-24 is composed of 12 protons, 12 neutrons, and 12 electrons. Magnesium - Protons - Neutrons - Electrons - Electron Configuration.

Since this atom is neutral the positive protons must be equal to the negative electrons. This atom will have 11 electrons. 2011-07-02 · A sodium ion (Na+) contains 10 electrons, 11 protons, and 12 neutrons.

All isotopes of oxygen have 8 protons. Having 8 protons is in fact the very definition of oxygen. the isotope number (18) is the sum of the protons and neutrons. Therefore, oxygen 18 has 10 neutrons. The number of electrons is a bit more complex,

Whichever you know, you subtract from the atomic mass. The 23Na+ has eleven (11) protons, twelve (12) neutrons, and how many electrons? | Yahoo Answers. Yahoo Answers is shutting down on May 4th, 2021 (Eastern Time) and beginning April 20th, 2021 The nucleus contains the majority of an atom’s mass because protons and neutrons are much heavier than electrons, whereas electrons occupy almost all of an atom’s volume. The diameter of an atom is on the order of 10 −10 m, whereas the diameter of the nucleus is roughly 10 −15 m—about 100,000 times smaller.

Na, sodium, atomic number 23. it's simple.A neutral Na atom has, u know, 11 electrons & 11 protons, 12 neutrons.When Sodium or in Latin, Natrium, has the symbol Na. Atomic Number = 11, Atomic Mass = 22.98, 11 protons, 11 electrons, 12 neutrons. First isolated by Davy in 1807 The atomic nucleus is made up electrically positive protons and electrically The electrons are the portion of the atom which engage in chemical reactions. For example: 1123Na or 2311Na The smaller number is always the Atomic numbe No. Protons. No. Neutrons. No. Electrons.

the number of neutrons should be the mass number (that big number with the ugly decimal) minus the atomic number. you should round the mass number to the carbon atom is made of protons, neutrons, and electrons. In this lesson, you will explore these subatomic particles and their charges.!!!!! 1.!Label the nucleus (protons, neutrons) and electrons in the drawing of a carbon atom above.
