An ion is an atom that has either gained or lost electrons. An ion has either a positive or negative charge, depending on whether it gained electrons (negative) or lost electrons (positive), while an atom is electrically neutral. When not part of a molecule, elements usually exist in an ionic form, the exception being the noble gases, or the elements on the leftmost column of the periodic table.
What else can I help you with?
How is an ion different from an atom of the same substance?
an ion has a full "shell"
What is the essential difference between an ion and an atom?
An ion is an atom that has a different number of electrons than normal. That makes it positively or negatively charged. Normally, atoms have the same number of electrons as they have protons. If the atom has lost one of more electrons, it will be a positive ion. If it has gained one or more electrons, it will be a negative ion.
Is an atom of an element with a different number of neutrons called ion or isotope?
ion
What do you call an atom that has gained or lost a proton?
An atom of a different element.
What are differences between ions and isotopes?
An ion is an atom with an electrical charge, positive or negative.An isotope of chemical element is an atom having a different number of neutrons.
Why is an iron atom attracted to sulfide ion but not to a zinc ion?
An iron atom is attracted to a sulfide ion because of the opposite charges between the two ions, creating an electrostatic attraction. In contrast, a zinc ion has a neutral charge, so there is no significant attraction between the zinc ion and the iron atom based on charge interactions.
How does the negative ion different from an uncharged atom of the same element?
the ion has a greater number of electrons
What is the difference between the formation of a positive ion and a negative ion?
positive ion forms when any electron removes from an atom and an anion called negative ion forms when an atom accepts an additional electron
What type of atom has a different number of protons and electrons?
An ion
What are atoms of the same element with different numbers of electrons?
Usually, an atom has the same number of protons as electrons, but when the number of electrons is changed, the atom is considered ionic. An atom that has lost an electron is called an anion, and an atom that has gained an electron is called a cation. One example of a cation is a potassium ion, or K+, and one example of an anion is chloride,(a chlorine ion) or Cl-
What atom has no balance between positive and electric charges?
No atom can have an imbalance in its charge; if it did, it would be an ion.
Is the number of protons the same in the atom or ion of lithium?
Yes, the number of protons in an atom and its ion of lithium is the same. Lithium always has 3 protons in its nucleus, regardless of whether it is in its neutral atom form (Li) or as an ion with a different number of electrons.
