To become stable. In other words, they gain ( or sometimes lose) electron to acheive a stable octet. In most cases, this would mean that the atoms are trying to have 8 electrons in their valence (outermost) shell of electrons. In other cases, ( helium and hydrogen) they just need 2 electrons in their outer electron shell. Methane for example. (formula CH4) ... Carbon has four electrons in its outermost shell ( it has two in the inner shell ... 6 total). It has four electrons so hence it is in group 4 of the periodic table. So carbon wants 8 electrons in its valence shell, that means that it has four more to go. Hydrogen has 1 electron in its outer shell and only needs one more. So, the carbon and the 4 hydrogens bond covalently. The carbon shares one electron from each of the four hydrogens ( 4 [ from itself] and 4 [ one from each hydrogen] = 8). So the carbon is satisfied. On the other hand, each hydrogen would share one of carbon's electrons to attain 2 each in their outer shell. So hydrogen is stable with its two electrons and carbon is stable with its 8. They gain electrons to become more stable.
p.s. Google covalent and ionic bonding.

When atoms loses or gains electrons it becomes a?
An ion.
Based on their placement on the periodic table what about ion formation is correct There is more than one correct statement?
A Group 6A element gains two electrons A Group 2A element loses two electrons A Group 3A element loses three electrons A Group 3A element loses three electrons group 1a element loses one electron group 7a gains one electron
An atom that gains or loses one or more electrons is it called an ion?
Yes, an atom that gains or loses one or more electrons is called an ion. When an atom loses electrons, it becomes a positively charged ion, known as a cation. Conversely, when it gains electrons, it becomes a negatively charged ion, referred to as an anion. This process of gaining or losing electrons allows atoms to achieve a more stable electron configuration.
What are electrically changed atoms called?
Electrically charged atoms are called ions. When an atom gains or loses electrons, it acquires a net electrical charge, resulting in a positive ion (cation) if it loses electrons or a negative ion (anion) if it gains electrons. Ions play crucial roles in chemical reactions and electrical conductivity in various substances.
Does the movement of electrons to atoms or from atoms make ions?
Yes, when electrons move from one atom to another, it can result in the formation of ions. If an atom gains electrons, it becomes negatively charged and forms an anion, while if it loses electrons, it becomes positively charged and forms a cation.
When atoms loses or gains electrons it becomes a?
An ion.
What heppens when a atom gains or loses electrons?
When an atom gains or loses electrons, it gains a negative or positive charge respectively. Atoms generally try to gain enough electrons to fill their outer, valence electron shell. For the first shell the number of electrons is 2 and for all others, atoms usually want 8 electrons.
How does atoms become charged?
An atom becomes charged when it gains or loses electrons to form an octet.
What do you get if an atom gains or loses protons?
If atoms gain electrons, negatively charged anions are formed. If atoms lose electrons, positively charged cations are formed.

What is formed when an atoms gains and loses electrons?
When an atom loses electrons, it becomes a positive ion Examples: Na --> Na+ + e- Mg --> Mg2+ + 2e- When an atom gains electrons, it becomes a negative ion Examples: Cl + e- --> Cl- O + 2e- --> O2-
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.

When an atom combines chemically with another atom it either gains loses or share what?
When an atom combines chemically with another atom, it either gains, loses, or shares electrons to achieve a more stable configuration. This process results in the formation of chemical bonds, which can be ionic or covalent depending on how the electrons are shared or transferred between the atoms involved.
When an atom gains or looses electrons what to the charge of atom?
When an atom gains electrons, it becomes negatively charged because it now has more electrons than protons. When an atom loses electrons, it becomes positively charged because it now has more protons than electrons.
What are the two main types of bonding?
Ionic bonds, in which an atom loses or gains an electron, and Covalent bonds, in which atoms share electrons.
