What can be said of the number of electrons of the one element can have?
A neutral atom of an element will have the same number of electrons as protons (atomic number). For example, the element magnesium has the atomic number 12, which means that a neutral magnesium atom will have 12 protons and 12 electrons.
What is the correct number of electrons in the second energy of magnesium?
8 electrons
How many electrons does the most common ion of magnesium Mg have?
The atomic number of magnesium is 12. The cation loses two electrons for 10.
What happens when a ionic bond forms between magnesium with an atomic number of 12 and oxygen with an atomic number of 8?
Two electrons are trasfered from magnesium to oxygen and ionic bond is formed.
What is the total number of electrons in a Mg2 positive ion?
The Magnesium atom will lose 2 of its electrons to become a Magnesium ion with 10 electrons. (Mg2+) How many electrons does a magnesium ion have? How many electrons does a fluoride ion have? How many electrons does a fluoride ion have?
What is the number of electrons and oxidation number of magnesium?
Singl atom has 12 electrons. Oxidation number of it is +2.
How electrons does magnesium have?
12 electrons in total as the atomic number of magnesium is 12
What is the atomic number of magnesium what does the number tell you?
The atomic number of magnesium is 12. The atomic number is equivalent to the number of protons and electrons in the atom.
What is the valency number of magnesium?
Valency is not a word... but if you want to know the number of valence electrons that Magnesium has, it is 2. Magnesium's atomic number is 12.
How many valence electrons does a neutral magnesium atom have?
12, the same as the number of protons indicated by magnesium having an atomic number of 12.
What can be said of the number of electrons of the one element can have?
A neutral atom of an element will have the same number of electrons as protons (atomic number). For example, the element magnesium has the atomic number 12, which means that a neutral magnesium atom will have 12 protons and 12 electrons.
How many electrons does an atom have with an atomic number of 12?
2 electrons there will be only 3 shells these shells are filled with electrons in this order; 2, 8, 8. But as you only have twelve there is no second eight it just has 2 electrons in that shell, lol well anyways the answer is two.
How many proton and electrons does the element magnesium have?
Magnesium has an atomic number of 12, therefore it has 12 protons, and therefore 12 electrons.
What is the correct number of electrons in the second energy of magnesium?
8 electrons
How many electrons does the most common ion of magnesium Mg have?
The atomic number of magnesium is 12. The cation loses two electrons for 10.
What is the number of atomic mass neutrons electrons protons in magnesium?
Magnesium has 12 protons and electrons and 12, 13 or 14 neutrons depending on the isotope; the atomic mass (conventional) is 24,305 amu.
The most stable isotope of an atom with 12 protons probably has neutrons?
Mass of protons + Mass of neutrons + mass or electrons - Binding energy of the atom. Do not forget to subtract the binding energy. If you teacher never mentioned this, then he/she is wrong. You always have to subtract the binding energy to find the real mass.
