Sodium is a metal (Na), what makes the Neutral atom of Sodium different from the lonized atom of Sodium

A neutral atom has more protons than an ion

Neutral atoms have more neutrons than an ion of an tom

Neutral atoms have a charge while ions do not

Neutral atoms have the same amount of protons and electrons while an ion has
either gained or lost an electron

What will most likely happen when two bromine atoms bond together?

The image compares the arrangement of electrons in two different neutral atoms. a figure labeled atom q has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has six black spheres. to the left of this figure is another figure labeled atom p. atom p has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has seven black spheres. which of the following best explains the position of the two atoms in the periodic table? atom p has an estimated zeff of 7 and is therefore to the left of atom q, which has a zeff of 6. atom p has an estimated zeff of 7 and is therefore to the right of atom q, which has a zeff of 6. atom p has an estimated zeff of 5 and is therefore below atom q, which has a zeff of 4. atom p has an estimated zeff of 5 and is therefore above atom q, which has a zeff of 4.
