What else can I help you with?
Two highly reactive elements in Period 4 are the metal potassium and the?
nonmetal chlorine. Both elements readily react with other elements to form compounds, with potassium giving up an electron to form a positive ion and chlorine gaining an electron to form a negative ion. Together, they form the ionic compound potassium chloride, which is commonly used as table salt.
What is always true of a binary compound?
A binary compound always contains two different elements. This means it will have a chemical formula consisting of two elements in fixed proportions. Binary compounds typically involve a metal and a nonmetal.
Hydrogen is a nonmetal and Oxygen is a nonmetal If these two elements were to bond they would form a?
When hydrogen, a nonmetal, bonds with oxygen, another nonmetal, they form a covalent bond. This results in the formation of a molecule of water (H2O), where the two atoms share electrons to achieve a stable electron configuration.
What non-metals can be bonded with metals to make salt?
The two elements that make the compound "salt", are sodium (metal) and chloride (non-metal). These two elements are bonded together to create sodium chloride as we call it "salt". Sodium particle-> O + O <-Chloride particle = Sodium chloride (salt).
What is an element that is highly reactive gaseous nonmetal?
Chlorine and fluorine, with fluorine more reactive. Some would also include oxygen. (The two remaining halogens are not gaseous at room temperature.)
What are the two elements which form acidic oxides?
Nonmetal elements such as sulfur and nonmetal oxides like carbon dioxide form acidic oxides.
Is H2O a metal or nonmetal?
H2O is neither a metal nor a nonmetal. It is a compound consisting of two nonmetal elements, hydrogen and oxygen.
Is SO3 a nonmetal or a metal?
SO3 is a compound and therefore is neither a metal nor a nonmetal, because these are types of chemical elements, not of compounds. This particular compound consists of two nonmetal elements, sulfur and oxygen.
Is CO2 a metal oxide or nonmetal oxide?
Carbon is a nonmetal. Thus this is a nonmetal oxide.
What are the two highly reactive elements in period 4?
the metal potassium and the nonmetal bromine
Which is hard thigh bone or tooth?
these are two different elements, thigh bone is "bone" and a tooth is enamel
Why is water not a metal or non metal?
In chemistry, the terms metal and nonmetal are reserved for elements. Water is a compound of two different elements: hydrogen and oxygen.
From what class(es) of elements is the following compound made nitrogen dioxide?
Nitrogen dioxide is composed of nitrogen and oxygen, which are both nonmetals. Therefore, nitrogen dioxide is made from nonmetal elements.
The most abundant elements in earth's crust are a nonmetal a metalloid and two metals what are the four elements?
The most abundant element in the earth's crust is a non-metal, oxygen. The second is the metalloid, silicon. The third and fourth are the metals, aluminum and iron.
What does a nonmetal elements need to do to form an anion?
A non metal must gain one or two electrons to form an anion
What elements are present in the following compound KI?
The compound KI consists of two elements, potassium (K) and iodine (I). Potassium is a metal, and iodine is a nonmetal.
Two highly reactive elements in Period 4 are the metal potassium and the?
nonmetal chlorine. Both elements readily react with other elements to form compounds, with potassium giving up an electron to form a positive ion and chlorine gaining an electron to form a negative ion. Together, they form the ionic compound potassium chloride, which is commonly used as table salt.
