It is not always easy to tell whether an atom will lose or gain an electron in a reaction. However, this is a general rule that applies in many cases. Simply put, the atom with the higher electronegativity will gain an electron and the atom will a lower electronegativity will lose an electron.

∙ 13y agoif the valency is positive (e.g. +1) then it looses electrons
if the valency is negative (e.g. -2) then it gains electrons
the number tells us how many electrons are transfered
NB electrons are negative

What Does the number of protons always equal to?
No An atom may have less, the same, or more neutrons than protons. The number of neutrons determine which isotope of an element you have. You do expect the number of protons and electrons to be the same however. If an atom loses or gains an electron to cause the number of electrons and protons to be mismatched we call that an ion rather than an atom.
Is the net charge of an atom always zero?
The net charge of an atom is always zero, because if an atom gains or loses electrons, causing it to acquire a net charge, we then call it an ion, rather than an atom.
What do you call the number that tells an element's location on the periodic table of elements?
Atomic number and it also tells the number of protons and electrons in an atom it is on top of the element symbol.
What do you call it when two or more atoms are touching?
If actually 'touching', I would think it was nuclear fusion. Two or more, sharing electrons would be an element or molecule, depending on the atoms.
What do you call an element that has lost an electron?
Elements that have gained or lost an electrons are called IONS. Ones that gained electrons (non-metals) and are therefore negatively charged, and known as ANIONS, and those that lost electrons (metals), are positively charged and known as CATIONS
What do you call an atom that gains or loses electrons?
An atom that gains or loses electrons is called an ion. If it gains electrons, it results in a negative ion called an anion. If it loses electrons, it results in a positive ion called a cation.
What do you call it when an atom loses and gains energy?
When and atom loses or gains enery, it becomes positivly or nevetivly charged and can become an ion.
What Does the number of protons always equal to?
No An atom may have less, the same, or more neutrons than protons. The number of neutrons determine which isotope of an element you have. You do expect the number of protons and electrons to be the same however. If an atom loses or gains an electron to cause the number of electrons and protons to be mismatched we call that an ion rather than an atom.
What do you call an atom When an atom losses or gains electrons its called an?
cell
Is the net charge of an atom always zero?
The net charge of an atom is always zero, because if an atom gains or loses electrons, causing it to acquire a net charge, we then call it an ion, rather than an atom.
When does an atom become ionized?
Why atoms form ions? Atoms form ionsin order to help another to obtain a full octet and to stabilize the valence shell. What happens when an atom forms a ion. charles jimingo
Which atom is electrically neutral?
All atoms are electrically neutral. If an atom gains or loses an electron, we call it an "ion" rather than an atom.
An atom that gains or loses electrons becomes?
Electrons have a negative charge, so they are usually written as "e-". When an atom loses an electron, the net charge on the atom increases.Suppose a hydrogen atom is hanging out (note that hydrogen is diatomic, but ignore that part for now) and somehow loses its electron. The electron will get taken up by something else with a positive charge (opposite charges attract each other). In general it would look something like the following:H -> H+ + e-This positively charged hydrogen (H+ on the products side) is considered a Cation (cation's are positive as they have a T in them that looks like a +, anions don't have a T so they are what we call negatively charged anions).
What do you call an atom that is both an ion and an isotope?
You call it an ion of that isotope. Let's use carbon-14 for example. If a carbon-14 atom gains/loses an electron, you simply call it a "carbon-14 ion".
Why doesn't the number of protons change for a single element while the neutrons and electrons can?
Because the no. of protons is the primary property through which we call an atom to be of a particular element.
What do you call the number that tells an element's location on the periodic table of elements?
Atomic number and it also tells the number of protons and electrons in an atom it is on top of the element symbol.
