Fluorine has 7 valence electrons, (9 altogether) and ten neutrons.
The element is Neon and the isotope is 10Ne19
The element with neutral atoms containing ten neutrons is neon. Neon has an atomic number of 10, so it always has 10 protons and 10 electrons.
The element that has 9 protons is fluorine. Its atomic number is 9, indicating that the element has 9 protons in the nuclei of its atoms. If there are 10 electrons, then the fluorine atom has gained an electron and is now a negatively charged anion with a charge of 1-.
The element with atomic number 56 is barium, a group 2 alkaline earth metal. Its atoms have two valence electrons in the 6s sublevel.

The element with 10 electrons and 10 neutrons is Neon. Neon has the atomic number 10, which corresponds to the number of electrons in a neutral atom, and its most common stable isotope has 10 neutrons.
yes, there will be 10protons and 10 neutrons in the nucleus(the middle) and there will be 2 electrons in the first valnce and 8 valence electrons in the 2nd valence.
The element is Neon and the isotope is 10Ne19
sodium has more protons and neutrons. electrons have practically no mass, valence electrons are just outer orbital electrons. sodium has 11 protons, 11 electrons, and 12 neutrons. Mass is 23. neon has 10 protons, 10 electrons, and 10 neutrons. Mass is just 20. The neon atom has 10 protons and 10 neutrons for a mass number of 20. The sodium atom has 11 protons and 12 neutrons for a mass number of 23. The number of valence electrons has no bearing on mass number or atomic weight.
Magnesium2+ because it donated 2 electrons

Uh... you left out the "following" part. Neon has 10 protons, 10 electrons, and 10 neutrons. It is a noble gas and has a full valence engergy level (2p) and satisfies its octet rule. Nobles gases are extremely stable, making it difficult to react them with anything.
