What type of ion is when an atom loses electrons?
A positive ion. Originally atoms have a neutral charge with equal amount of electrons and protons. If atom loses electrons, it still has the same amount of protons so it becomes a positive 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-
Is an atom with 12 protons 12 electrons and 12 neutrons an ion?
No. The number of protons and electrons is the same, resulting in a neutral atom (magnesium in this case). In order to be an ion the number of protons and electrons must be different.
How many electrons do calcium has?
Calcium, as an element, has 20 electrons. But when becomes an ion, it loses two electrons, becoming Ca+2. Therefore, as an ion, calcium has only 18 electrons.18
What can be concluded if an ion of an element is smaller than an atom of the same element?
The ion is positively charged because it has fewer electrons than the atom.
Does an atom of neon have the same electrons as an atom of CI-ion?
No - but it has the same as a F- ion
An atom can become an ion by losing?
An atom can become an ion by losing electrons. It can accomplish the same thing by gaining electrons.
What do an ion of Ca2 plus and an atom of Ar have in common?
They have the same number of electrons. A neutral Ca atom would have 20 electrons but because it is a Ca2+ ion it only has 18 electrons (the same as Ar).
An atom in which the electrons are not the same number as the protons is called an?
Ion.
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.
How does the negative ion different from an uncharged atom of the same element?
the ion has a greater number of electrons
How does a negative ion differ from an uncharge atom of the same element?
the ion has a greater number of electrons
How is a strontium atom different from a strontium ion?
An isotope has extra or fewer neutrons in the nucleus than the average number for that element. This may or may not result in a radioactive isotope. An ion has extra or fewer electrons orbiting the nucleus. This usually increases the chemical reactivity.

How does the composition of an ion differ from the composition of a non ionic particle?
An ion has a net electrical charge; a nonionic particle that is at least as large as an atom does not.
What determines if an atom is an ion?
An atom is electrically neutral; it has the same number of positively charged protons as it has negatively charged electrons. If an atom either gains or loses one or more electrons, then it will have an electric charge, and will be an ion.
