A sodium ion differs from a sodium atom in that the sodium ion?
A sodium ion differs from a sodium atom in that the sodium ion has a missing electron electron. It has a positive charge, as opposed to the atom, which is neutral.
Which diagram best represents the relationship between the diameter of a sodium atom and the diameter of a positive sodium ion?
A diagram showing the sodium atom as larger than the positive sodium ion would be representative since the positive ion has lost an electron, leading to a decrease in size due to the loss of electron-electron repulsion.
How do sodium atom and a positive sodium ion differ?
The sodium ion has less electrons than protons whereas the sodium atom has an equal amount of protons and electrons
How does sodium atom form an ion?
When a sodium atom forms an ion, it loses one electron from its outer shell. This loss of an electron leaves the sodium atom with a positive charge, as it now has one more proton than electrons. This results in the formation of a sodium ion, specifically a sodium cation with a charge of +1.
What does a sodium atom become when it loses its only valence electrons?
Sodium ionSodium, Na, becomes a single positive cation Na+
When a sodium atom becomes an ion it does what?
A sodium atom would lose a electron so it would become a Na+ ion
When sodium forms an ionic bond with chlorine the sodium atom donates an electron to chlorine and becomes a 19 charged ion?
Actually, when sodium forms an ionic bond with chlorine, the sodium atom donates one electron to chlorine, resulting in the formation of a positive sodium ion and a negative chloride ion. The sodium ion becomes Na+ and the chloride ion becomes Cl-.
Is the size of a positive ion generally bigger or smaller than the size of the neutral form which it forms?
A positive ion is generally smaller in size than the neutral form from which it forms. This is because when an atom loses an electron to become a positive ion, the remaining electrons experience a stronger attraction to the nucleus, leading to a more compact arrangement.
What is the ion formed by a sodium atom called?
Sodium, Na, is in group 1 of the periodic table, so to achieve a complete valence shell, it forms a cation with a charge of 1, Na1+.
What happens when a sodium atom loses an electron in its outer energy shell?
it becomes a positive ionit becomes a positive ion
How does a sodium atom combine with a chlorine atom?
The sodium atom loses its valence electron to the chlorine atom forming a positive sodium ion and a negative chloride ion. The two are attracted to each other because of their opposite charges.
What happens when a sodium atom loses an electron in its outer energy?
It becomes a positive ion.
