That isn't necessarily true. The Halogens (group 17) follow what you said, but the Alkali metals (group 1) don't. As you go down the column, the elements get more reactive for group 1; Lithium is the least reactive and Francium (speculated) is the most reactive. On the other hand, as you down the Halogens, they do get less reactive. Astatine (speculated) is the least reactive while Fluorine is the most reactive element of them all. Hope that clears up things!
Atoms with fewer than 4 outer electrons tend to lose electrons to achieve a stable electron configuration rather than lend them. This results in the formation of positively charged ions. Atoms with 4 or more outer electrons tend to gain electrons to fill their outer electron shells and form negatively charged ions.
Valence electrons determine how easily an atom can bond with other atoms. Atoms with a few valence electrons are more likely to lose or gain electrons to achieve a stable electron configuration, making them more reactive. The number of valence electrons also influences the type of chemical bonds an atom can form with other atoms.
Halogens become less reactive as you go down the group. This is because atomic size increases down the group, making it more difficult for the larger atoms to gain electrons and react with other substances. Conversely, smaller halogen atoms are more reactive because they can more easily gain electrons and form bonds with other elements.
Two valence electrons make an atom chemically reactive because it wants to either gain or lose electrons to achieve a full valence shell. This makes it more likely to form bonds with other atoms to reach a stable electron configuration.
An atom that has fewer than 8 valence electrons is more reactive, or more likely to form bonds, than an atom with 8 valence electron. Atoms bond by gaining, losing, or sharing electrons in order to have a filled outermost energy level with 8 valence electrons.
More the number of shells in an atom, more away will be the electrons from the nucleus. Hence, weaker will be the attraction between nucleus and outermost electrons. So atom with more shells will let go their electrons easier than atoms with fewer shells.
That isn't really true. What makes atoms more reactive is if their electronic configuration is nearly that of a noble gas -- in other words is either has just one or two electrons less or more than a noble gas.So elements with either 1, 2, 6 or 7 valence electrons tend to be especially reactive.so the guy who gave the first answer doesnt know what hes talking about.
No! Atoms with more than 4 electrons gain electrons during bonding. Atoms with less than 4 electrons tend to lose electrons during bonding. Hope this helps!
Valance electrons means that the element has not reached the octet configuration and is therefore reactive the reactivity depends on the no. of valance electrons the more valance electrons the more unstable the atom is and the more reactive it is.The gasses like helium neon xenon are all inert which means they have an octet configuration and have no delocalised or valance electrons.

Cations are positively charged ions formed when atoms lose electrons. So they have less electrons than protons. Anions are negatively charged ions formed when atoms gain electrons. So they have more electrons than protons.
They may either form covalent or ionic bonds with more atoms.
If I recall correctly, it's because they don't have any electrons in their atoms. Atoms react in order to get a full set of 8 electrons, and the less electrons an atom has, the more likely they are to react.
Atoms that don't have a full octet are typically those that have fewer than eight electrons in their outer shell, which can make them more reactive. Examples include hydrogen, lithium, and beryllium, which can form bonds to achieve a stable electron configuration. Additionally, elements like boron may also have incomplete octets, often forming compounds where they share electrons with other atoms. These atoms tend to seek additional electrons through chemical bonding to reach a more stable state.

Elements are usually reactive when they have fewer electrons in their outermost energy level than is needed to achieve a stable configuration. This leads to them readily gaining, losing, or sharing electrons in order to attain a full outer shell and become more stable.
