Respuesta :
The chemical symbols for three different atoms or atomic anions with 9 electrons are Neon (Ne), Florine (F⁻¹) and Oxide (O⁻²).
What is atom?
An atom is the smallest unit of matter, consisting of the positively charged nucleus and the electrons which move around it. The atom can not be divided further.
The atom of a matter is made by three elements-
- 1) Neutron-Neutron is the element of an atom, which has zero charge.
- 2) Proton-Proton is the element of an atom, which has a positive charge.
- 3) Electron-Electron is the element of an atom, which has a negative charge.
The chemical symbols for three different atoms or atomic anions with 9 electrons has to be write down. Anion is the element which has more number of electron compare to its protons.
This makes the element negatively charged. Neon (Ne), Florine (F⁻¹) and Oxide (O⁻²) are the element which have atomic anions with 9 electrons.
Thus, the chemical symbols for three different atoms or atomic anions with 9 electrons are Neon (Ne), Florine (F⁻¹) and Oxide (O⁻²).
