Such atom attracts electrons pair more powerfully as compare to other covalently bounded atom and acquires a partially negative charge.
For metals high electronegativity mean low reactivity; for halogens, C, O, N, S, etc. the meaning is high reactivity.
It is more likely to attract electrons. :)
It told them that the atom was mostly empty space.
The largest atom is francium. It is not possible to tell the largest molecule as it will be generally polymeric.
An atom with high electron affinity is more likely to react with an atom that has low ionization energy. This is because low ionization energy indicates that the atom can easily lose an electron, making it more reactive and able to engage in bonding with an atom that has a strong attraction for electrons. Conversely, an atom with high ionization energy is less likely to readily lose electrons, making it less reactive in this context.
It is an anion.
For metals high electronegativity mean low reactivity; for halogens, C, O, N, S, etc. the meaning is high reactivity.
The francium atom is larger.
It would tell you how many neutrons make up the Nucleus of the atom.
The atom also has 15 electrons.
Electron
you can tell an atom has a negative charge if its outer shell is not stable(happy)/full
If the number of protons and neutrons are the same, its an atom, if not its an ion
It can fuse with another atom.
Tell you the number of protons and electrons in an atom
that the atom mostly consisted of empty space
It is more likely to attract electrons. :)
