What metals react with other metals what happens to the valence electrons of the metal atoms?
== == When metals react with other elements, the atoms of the metals give up their valence electrons.
Why do noble gases not react with other compounds and elements?
Noble gases don't react with other elements because of the stability of the outer hell. Helium has 2 electrons , 1s2 a full shell. the restt have an outer shell of 8 electrons the "octet". This gives neon a full valence shell, the rest of the heavier noble gases have an outer shell with 8 electrons which while it is is very stable and makes these gases very un-reactive it is not full.Compounds have been made for the noble gases heavier than neon. These compounds are all unstable and highly reactive and the first a xenon fluoride was made in 1962.
When the elements on the Earth combine to give compounds how many are there likely to be Eg hundreds thousands or millions?
There are millions of possible compounds that can be formed when elements combine on Earth. This is because elements can bond in various ways and proportions, leading to the creation of a wide range of different compounds with diverse properties and characteristics.
What other chemicals does europium react with?
Europium is the most active of the lanthanides. it reacts quickly with water to give off hydrogen. it also reacts strongly with oxygen in the air, catching fire spontaneously. Scientists must use great care in handling the metal.
Are elements always pure?
Yes, elements are considered pure matter. This is because atoms exist of one type of atom. This means that all atoms in an element have the same number of protons (and electrons when the atom is not ionized).

How is elements related to compounds?
Elements are the "building blocks" used to "build" compounds. Elements are the "letters of the alphabet" with which the "words" of compounds are "written". Not perfect analogies, but they should give you an idea.
What metals react with other metals what happens to the valence electrons of the metal atoms?
== == When metals react with other elements, the atoms of the metals give up their valence electrons.
Does helium react with other chemicals?
Helium does not react with any elements at normal circumstances because all the vacant spaces of the outer electron shell are filled. It will not normally give up or gain electrons but ions of helium may react with other elements.
How do the parts of an atom combine to form compounds and mixtures?
It's not the atoms that change, it is the molecules... In short, the molecules(elements) can share, give, or take electrons from other molecules(elements).
Why are nobel gasses not found in compounds?
The nobel gasses can be made to react under somewhat extreme circumstances, but they do not readily react on their own with other elements because they have a complete outer shell, which is to say they have 8 electrons in their highest energy level. This means they are completely stable, neither looking to borrow electrons, nor to give any away.
Why do onions cry?
Onions contain sulfur compounds (which also give them their characteristic smell). The compounds are gases and are released when onions are cut. These gases react with the water in the tears in the eyes to form other acidic compounds which irritate the eye and cause crying.
