How many electrons gained or lost for calcium?
Ca loses electrons. In general metals react in compound by losing some of their electrons, Ca is a metal.
What charge does an ion have?
An ion is an atom or molecule which has lost or gained one or more valence electrons, giving it a positive or negative charge.
What does -ion mean?
An ion is an atom with a positive (+) or negative (-) charge. This is because the atom has a different amount of electrons than its number of protons (aka atomic number).
An atom that has gained or lost electrons and thus carries an electrical charge?
An atom that carries an electrical charge because it has gained or lost electrons is called an "ion". An atom that has gained one or more electrons, and has a negative electrical charge, is called an "anion". An atom that has lost one or more electrons, and has a positive electrical charge, is called a "cation". The term "ion" is used to refer to both cations and anions collectively or non-specifically.
Silicon how many electrons are gained or lost?
it has gain 4 electrons
Charge of an atom that has gained electrons?
It is a negative charge
What is the charge on an atom that has gained 5 electrons?
Each electron has a 1- charge, so an atom that has gained 5 electrons has a charge of 5-.
What charge does an atom that has gained electrons?
Positive
When an object gains or loses electrons has it an electric charge?
That depends entirely on sign of the charge. If the object gains a positive charge, then that means the object as lost electrons, since electrons are negatively charge. If the charge is negative, then the object has gained electrons. It is also possible that the charge was created by a movement in protons, which are positively charged, in which case the object may not have lost or gained electrons.
What charge would nitrogen have if it gained 3 electrons?
Nitrogen would have a neutral charge and eight valence electrons.
A charge atom that has gained one or more electrons?
An ion is a charged atom that has gained or lost one or more electrons. An ion has an unequal number electrons and protons giving it either a positive or negative charge.
What are Atoms that carry an electrical charge called because they have gained or lost electrons?
Atoms that carry an electrical charge because they gained or lost electrons are called ions. An atom that has lost electrons will be positively charged, and it is called cation. On the other hand, an atom that has gained electrons will be negatively charged, and it is called anion.
How many electrons must be gained or lost for calcium to attain a noble-gas electron configuration?
two electrons lost
What is the charge on a single atom that has not gained or lost electrons?
Such an atom would be neutral - no electric charge.
What is an atom that has an electric charge because it lost or gained electrons?
An atom that carries an electrical charge because it has gained or lost electrons is called an "ion". An atom that has gained one or more electrons, and has a negative electrical charge, is called an "anion". An atom that has lost one or more electrons, and has a positive electrical charge, is called a "cation". The term "ion" is used to refer to both cations and anions collectively or non-specifically.
When an element loses an electron what happens to the charge of the element?
When "x" valence electrons are lost the charge is +x When "x" valence electrons are gained the charge is -x for example, if chlorine gained one electron, the charge would be Cl 1- or, if magnesium lost two electrons, the charge would be Mg 2+
What is an atom that has gained or lost electrons and carries an electrical charge?
an ion
