the elements which have 1, 2 or 3 electrons in their valence (outermost)shells are most likely to lose electrons compared to the other ones and we name them as metals and alkaline earth metals. these elements want to give their outermost shell electrons to become more stable. because when they give those electrons the next shell under this one which has 8 electrons (2 in some cases such as lithium) becomes the new valence shell so the electron configuration resembles a noble gas.
Nonmetals become stable by gaining or sharing enough valence electrons to have a set of eight valence electrons in a shell or energy level
Nobel gasses.
Every element that isn't a noble gas, wants to become isoelectronic or have the same number of electrons as its nearest noble gas. This is because noble gases are very stable, while other elements aren't. Forming compounds allows elements to gain or lose electrons, which allows them to become like their nearest noble gas.
The periods near the top, i presume because they have less shielding from other electrons in their orbitals, therefore there will be a larger nuclear pull so easier to attract electrons. Obviously a element with a full shell or 1 or 2 electrons in it isn't really going to gain electrons and Transition metals are weird. Hope this helps :)
Carbon is the "utility player" of chemistry, and can bond in many different ways with other elements. It generally shares electrons covalently with other non-metals, usually hydrogen, oxygen, and nitrogen. It doesn't typically lose or gain them (but can in certain situations.)
A metalloid :)
lose
They can either lose or share electrons when they combine with other elements. So, depending on the conditions , these elements can behave as either metals or nonmetalss. Durr !
Metals are likely to make anions. So they lose electrons to get a positive charge. The other elements gain electrons and get negatively charged.
Because gold is an element a pure substance cannot be created by combining other elements
Jaaliyah is a modern invented name with no specific meaning. It is likely derived from combining sounds or elements from other names.
By combining or mixing elements
noble gases, or inert gases they are the same thing and they are group 18 they have full valence electrons so they are unlikely to react with other elements
they share electrons with the other atom they're combining with
Chemical compounds are formed by the combining of elements or other compounds through chemical reactions. They are defined as pure chemical substances.
It can both gain and lose electrons depending on the different elements. With hydrogen, it gains electrons to produce hydrogen sulphide and it will lose electrons with oxygen to produce sulphur oxides. Generally it will tend to gain electrons as it is in group 16 of the elements and so is quite negatively electrovalent but against a more negatively electrovalent elements it can be forced to lose electrons unwillingly as in the case of oxygen. Even though oxygen is also in group 16, sulphur is an order below oxygen and therefore less negatively electrovalent that oxygen.
Elements react with other elements based on the number of electrons in their outer shell, also called valence electrons.
