Why atom tend to give up electrons during the process of chemical combination possesses?
Atoms both give up and receive electrons in the bonding proccess. The determining factor is simple how many electrons said atom has in it's outer shell. All atoms strive to be bear a full outer shell or a stable octet. Electrons arange themselves into shells around an atom, 2 in the first, 8 in the next two. If an atom has two electrons in its second shell it is simpler for it to loose two electrons to acheive a full shell then to gain six. Conversly if it has seven electrons in its third shell it will exept one more to fill its shell. i hope this helps and if anyone has a more correct response please be kind.
What kind of electrons move into an atom?
positive
When 2 oxygen atoms come together they form what kind of bond?
When two oxygen atoms come together, they form a covalent bond by sharing electrons. Each oxygen atom has 6 electrons in its outer shell, and by sharing two pairs of electrons, they can achieve a stable configuration with a full outer shell of 8 electrons.
Does the number of electrons in an atom ever change?
This is kind of a trick question...An atom has a fixed number of electrons. However, some atoms are predisposed to give up or accept electrons to ensure their outer shell is full. When that happens, though, they are no longer atoms, but become ions. An ion is a charged atom.For example: Chlorine has an outer shell that is one electron short of a full shell. It readily accepts an electron from anything that will donate it. In doing so it goes from being a Chlorine atom to a Chlorine ion with a negative charge.Sodium has one electron in its outer shell. If it loses it it has a full outer energy shell and is more stable. It readily goes from being a sodium atom to being a sodium ion with a positive charge.Hence the trick question. Yes an atom can change the number of electrons it has, but as soon as it does so it stops being an atom and becomes an ion. Or, conversely, no, an atom cannot change its number of electrons because when it does so it stops being an atom and becomes an ion. Take your pick!
How many valence electrons are in a hydrogen ion?
It depends on what kind of ion:If it's a cation (H+) then there is 1 proton and 0 electrons, so zero.If it's an anion (H-) then there is 1 proton and 2 electrons, so 2 (and that shell is full).
What is a synonym for valence electrons?
'Electrons in the atom's outer shell'. There isn't really a synonym for this kind of thing.
What kind of electron determines if a compound is covalent or ionic?
These are the electrons from the outer shell of an atom.
What kind of bond holds hydrogen atoms together?
It is a covalent bond. Each hydrogen atom wants to have a full outer shell of 2 electrons. As each atom has only 1 electron in its shell they can share the electrons between them.
What kind of outer shell is each atom in a covalent bond left with?
In a covalent bond, each atom retains its outer shell of electrons. The atoms share pairs of electrons to achieve a full outer shell, which makes the bond stable.
When electrons are transfered between the atoms of metallic and nonmetallic elements what kind of bonds are formed?
When a metallic atom and a nonmetallic atom have an electron transfer to form an ion, this is known as an ionic compound. For example, salt (NaCl) an electron transfer occurs. The Na, which has 1 electron on its valence shell ( outer shell) and the Cl, which has 7 electrons on its valence shell. The Na transfers its one electron to the Cl. This therefore results in the Cl having a full valence shell; at this point Cl is negative and Na is positive. We can then conclude the NaCl is an ionic compound.
What kind of bond is formed when electrons are transferred to one another?
An ionic bond forms when one atom transfers electrons to another atom. When this occurs, the atom that loses the electrons becomes a positively charged ion and the atom that gains the electrons becomes a negatively charged ion. The oppositely charged ions form an electrostatic attraction to one another, which is the ionic bond.
What kind of chemical bond is formed when atoms gain or lose electron?
Ionic bonding is when one atom gives up 1 or more electrons from its outer shell to another atom's outer shell.
