If an atom gives up an electron does it it have a positive charge?
Yes. It becomes a cation (a positive ion). Yes. Each positively charged proton in the nucleus must be cancelled out by a negatively charged electron, or else any noncancelled proton's positive charge will give its atom a positive charge. Likewise the atom that gains the lost electron will have more negatives than positives and will gain a negative charge.
How many electrons are in valence shell of a sodium atom before and after reaction with chlorine gas to give sodium chloride NaCl?
A sodium atom has 1 electron in its valence shell, while a chlorine atom has 7 electrons in its valence shell. When sodium reacts with chlorine to form sodium chloride, the sodium atom loses its 1 electron to achieve a stable octet configuration, while the chlorine atom gains this electron. The resulting sodium chloride molecule has 8 electrons in the valence shell of the chlorine atom.
How is an ion formed?
An ion is formed when an atom gains or loses an electron in bonding with another atom, causing the atom to become a positive or negative ion. Since electrons are negative, if an atom loses an electron, there are more protons (which are positive) than electrons, which causes the atom to become a positive ion (sometimes called a cation.) If an atom gains an electron it becomes a negative ion (or anion.) Ions are most commonly formed when two elements undergo ionic bonding, in which the elements 'give and take' electrons to gain full outer shells.
A postitvely charged praticle in an atom is called a?
The answer is an ion. An ion is what is left when the process of ionization has occured. Ionization is when an atom either gains or loses an electron, depending on the amount in its outer shell. There are many ways for this to happen including reacting with other atoms or absorbing radiation. An electron has a charge of 1-, therefore gaining an electron gives the ion a charge of 1- and losing an electron gives the ion a charge of 1+
What kind of atoms would typically form ionic bond?
Metal and nonmetals form ionic bonds. The metal atom will give one or more electrons to the nonmetal atom. This is so that they can both have full electron shells. But by donating and accepting electrons, the metal becomes a positive ion as it has more protons than electrons, and the nonmetal becomes a negative ion as it has more electrons than protons. For instance, sodium chloride (salt). The sodium (metal) gives an electron to chlorine (nonmetal). By getting rid of one electron, the metal atom gains a full outer electron shell, and by accepting three electrons ( from 3 sodium atoms), the nonmetal atom also gains a full outer electron shell. But they both become ions. Hope this helps ( I'm only 14)
What does a halogen atom give off when it gains electrons?
NOTHING

What is the charge of a valance electron?
The charge of a valence Electron is negative. The word valence means the combining power of atoms: the combining power of atoms or groups measured by the number of electrons the atom or group will receive, give up, or share in forming a compound. Therfore nothing changes the electrons charge. The electrons charge will always be negative no matter what. Electrons make up the stable atoms. If it the atom gains or looses an electron it becomes either a positive (looses an electron) or negative (gains an electron) ion.
When will an atom give up an electron?
An atom will give up an electron when it is more stable by achieving a full outer electron shell. This typically occurs when the atom is in an ionic bond or is trying to achieve a more stable electron configuration.
Which type of atom becomes positive and why?
an atom becomes positive when that atom gives their electron to other atom....when the atom reacts it is called ion not atom... so that means that ion has charge of ion+..... atom has to give or take( in this case give) electron to make their outer most shell full

What are electrovalent compounds give definition with examples?
(Chemistry) a type of chemical bond in which one atom loses an electron to form a positive ion and the other atom gains the electron to form a negative ion. The resulting ions are held together by electrostatic attraction Also called ionic bond.example of electrovalent compound is NaCl (Sodium Chloride)
You can see an atom with?
No device can give the complete structure of an atom but you can get a minute idea about the look of an atom using an Electron Microscope!
How many electron does barium have to give up to achieve a noble gas electron configuration?
Two electrons
What is gained or lost in an atom to give it an electrical charge?
Electron(s).
