Beryllium is a stable element.
Tighten terminal. If terminal is worn (will not become tight at all), replace.
Other words for "become less tense" include: * relax * calm down * "chill out" (slang) * take it easy * loosen up * unwind * cut loose
loose
Tap on your 1998 Mazda brake rotors with a hammer or mallet until they become loose. The brake rotors will simply slide off.
it is not a cracked engine block it is just a loose block
Metals will LOSE electrons to become stable.
All the atoms in the universe have a tendency to become stable by having 2 or 8 electrons in their outermost cells. So, if an atom has very few electrons i.e 1,2,3 or 4 electrons in it's outermost cell it will tend to loose electrons in order to become stable. hope it helps!
the combining capacity of an atom is called valency
Neon is stable in nature. It has completely filled octet.
No, it is not true. When metals loose electrons they become cations.
Yes, it is. Since valency is the no. of electrons an element should gain or loose or share to become stable. So, this is true in case of substances which form ions. But elements like carbon never form ions. Its valency is four. It shares electrons to get stable.
they add or loose electrons from the outer most shells
Potassium (K), an Alkali Metal in Group 1 with atomic number 19, has a single valence electron in its outermost shell. Therefore it only needs to lose one electron in order for the element to become stable.
Yes is is non reactive because of the electrons that are on the exterieur energetique layers of its atome. The attomique number for aluminum is 13 meaining it has 3 valence electrons ( 3 electrons on its outer layer). When an element does not have a completed exterieur energetic layer it is unstable, so it tries to gain electrons or loose electrons to become stable ( to be stable you need to have 8 electrons on the outer layer). So in this case aluminum wants to become stable, by loosing three electrons, but the ponostrophic energy required to loose them is to high, so it basicly gives up until it can react with a moleculos element, which is a whole different topic.
Noble gases have eight electrons in their outermost (valence) shell (an octet)and due to this they are very stable so they don't need (or want) to loose or gain electrons to be stable and thus don't take part in chemical reactions and don't form any negative or positive ions.
Sodiumbeing in group 1 needs to loose 1e- to become stable. Chlorine being from group 17 needs to gain 1e- to become stable. Sodium gives its extra electronto the chlorine atom. Now both have 8 electrons in their valence and are stable. The sodium gets a positive charge because it lost and electron. The chlorine gets a negative charge because it gained an electron.This creates an ionic bond
conduction band electrons detach themselves from atoms and become delocalized
