Everything around us is made up of different elements. The air has Oxygen and Nitrogen. Plants and people have lots of Carbon. Helium is in balloons. Hydrogen is in water. Open the Symbol screen, then explore to develop your own ideas about how the atomic particles determine the name of an atom or ion. Explain your understanding: 5. What determines the element

Due to protons and electrons number.

Explanation:

The atomic particles determine the name of an atom or ion by number of protons because the number of protons determines the atomic number of an element and this atomic number distinguishes one element from another and number of electrons also be different in atoms of the same element due to chemical bonding, due to which ions are produced. So we can say that atomic particles such as proton, electron and neutrons determine the name of an atom or ion.

sodium (na), for example, has one electron in its valence shell. this is an unstable state because that valence shell needs eight electrons to be full. in order to fill its valence shell, find a way to add seven electrons to its valence shell
