What is the element with 11 protons and 12 neutrons?

What is the element with 11 protons and 12 neutrons?

Sodium
Sodium has a mass number of 23amu. Since sodium has 11 protons, the number of neutrons must be 23 – 11 = 12 neutrons.

What is an atom with 12 protons and 11 electrons?

The sodium atom contains 11 electrons, 11 protons, and 12 neutrons.

What is the atomic number of the atom that has 11p 11e and 12n?

The number of protons determines the atomic number. The 11 protons makes an atomic number of 11. Sodium 2311Na is the most common isotope of sodium.

What element has 12 neutrons and metallic has 11 electrons?

Sodium has a mass number of 23 and an atomic number of 11. It contains 11 protons, 11 electrons, and 12 neutrons.

What is the element with 12 protons?

magnesium
On the periodic table of elements, magnesium is represented by the symbol Mg. It has an atomic number of 12 because it has 12 protons in its nucleus.

What is the nuclear symbol for an atom that contains 11 protons 11 electrons and 12 neutrons?

Z specifies the identity of the nucleus. If Z=11 , then the element is sodium. We would thus describe this species as 23Na .

What is the mass number of an atom with 11 protons 12 neutrons and 11 electrons?

The atomic number is 11. The mass number is 23.

What is the charge of an atom that contains 11 protons 12 neutrons and 11 electrons?

The term we would use for this element is 23Na . 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.

What is the atomic number of a neutral atom with 11 protons 12 neutrons and 11 electrons?

What is the mass of an atom if it has 11 protons 12 neutrons and 11 electrons?

The mass number is 23.

What isotope has 12 protons and 14 neutrons?

Mg-24 (12 neurtrons) is 78.9%, Mg-25 (13 neutrons) is 10% and Mg-26 (14 neutrons) is 11.01%, of all the Magnesium found in nature.

What is the atomic number of an element with 12 protons 10 neutrons and 12 electrons quizlet?

Magnesium has an atomic number 12, mass number 24, 12 protons, 12 neutrons, 10 electrons, and charge of +2.
