What else can I help you with?
Elements are classified as either?
metals, semimetals or nonmentals
Why does potassium and oxygen pair atoms including a medal and nonmetal?
If by "pair atoms" you mean molecules, and by potassium and oxygen you mean potassium oxide, then molecules can not be described as metals or nonmentals. Potassium is a metal, while oxygen is nonmetal.
What is this bond that is usually demonstrated by nonmentals?
The bond you are referring to is likely a chemical bond, which is the force that holds atoms together in molecules. Nonmetals commonly form covalent bonds, in which they share electrons to achieve stability. This sharing of electrons allows nonmetals to achieve a full outer electron shell and form stable compounds.
What percent of metals and nonmentals does your body contain?
The human body is composed of about 65% metals, such as iron, zinc, and copper, which play essential roles in various biological processes. Nonmetals make up the remaining 35%, including elements like oxygen, carbon, and hydrogen, which are crucial for sustaining life through processes like respiration and metabolism.
Where are the most nonmentals found in the periodic table?
The nonmetals are typically found on the right side of the periodic table, with the elements in Group 17 (halogens) and Group 18 (noble gases) being the most prominent nonmetals. Elements such as fluorine, chlorine, oxygen, nitrogen, and helium are examples of nonmetals.
Which family do the most active nonmentals belong to?
The most active nonmetals belong to the halogen family, which includes elements such as fluorine, chlorine, bromine, iodine, and astatine. Halogens are highly reactive due to their strong tendency to gain an electron to achieve a stable noble gas electron configuration. Among them, fluorine is the most reactive nonmetal. These elements are commonly found in nature in various compounds rather than in their elemental form.
Elements that typically attract electrons are what?
include the halogens are nonmetals
Which element would be most likely to gain electrons in a chemical bond?
The Halide gasses (Fluorine, Chlorine, Bromine etc. ) because they only need to gain 1 electron to fill its outermost energy level.
Which type of element donates the electron?
Fluorine is the element that would most likely to gain electrons in a chemical bond Metals ususally give electrons, and nonmentals usually gain electrons.
How can an elements property be predicted?
The Periodic Table (see link) gave great insight into the chemical properties of all the elements ... for it turns out that there is a pattern to it all. For predicting its chemical reactivity, generally you look at where it lies on the periodic table, which groups it with metals, semimetals, or nonmentals. Metals combine with nonmetals to form ionic compounds; nonmetals also combine with other nonmetals to form covalent compounds; and metals combine with other metals to form metal alloys (semimetals have intermediate properties). The element's location on the periodic table also defines its specific valence electron structure, and since atoms tend to react so that they have a full octet of valence electrons this will predict the specifics of its bonding behavior. For example, a metal that has only two valence electrons (like nickel) will tend to create a (+2) cation. A nonmetal that has four valence electrons (like carbon) will tend to form four (covalent) bonds.
Do elements in group 2A gain or loose electrons when they become ions?
Lose 2Alkaline-earth metals have 2 outer shell electrons. All atoms "want" eight. They will achieve a full outer shell by losing or gaining the least number of electrons. Since group 2A elements have two valence electrons, they would either have to gain 6 electrons or lose 2. It is easier to lose 2.
