Give an examples of the three kinds of chemical bonding?
Ionic bond covalant bond hydrogyn bond
how many hydrogen atoms must be bond to silicon to give it an octet of valence electrons?
Silicone has 4 valence electros so it would need 4 hydrogen atoms to give itself an octet of valence electrons.
Characteristics of a neutral substance?
They don't readily give or recieve hydrogen atoms.
When atoms combine the force of attraction that holds them together is an?
When atoms combine, the force of attraction that holds them together is called a chemical bond. This bond forms when the atoms share, give, or take electrons to achieve a stable electronic configuration. The type of bond formed (ionic, covalent, or metallic) depends on the difference in electronegativity between the atoms involved.
What is a mole and give its concept?
A mole is a quantity of substance which has Avogadro's number of molecules or atoms in it.
What are the physical properties of a substance give three examples?
Examples: density, hardness, boiling point, refractive index.
What is toxicant and give examples?
substance that produce adverse biological effect such as lead
Do metals take electrons or give electrons to the atoms they bond with?
Metals give up electrons while non-metals gain electrons
When substance give off light or another form of electromagnetic radiartion when they absorb energy?
The substance is said to exhibit luminescence. This phenomenon occurs when the absorbed energy is released in the form of light or electromagnetic radiation as the atoms return to their normal state. Examples include fluorescence, phosphorescence, and bioluminescence.
How can two atoms form a covalent bond?
Two atoms can form a covalent bond (also called molecular bond) by bonding a non-metal with another non-metal. These non-metals can be found on the far right side of the periodic table (as well as hydrogen). When the atoms interact, neither atom is willing to give away its electrons, therefore when the atoms bond together, they share their valence electrons, whereas ionic compounds gain and lose valence electrons. .
What is a pure subsatce whose smallest unit is made up of atoms of more than one element?
Compounds have atoms of more than one element.Covalent Compounds have covalent bonds between the atoms as in Water (H2O), or methane (CH4).Ionic Compounds have ionic bonds between the atoms such as Salt (NaCl) which will dissociate into ions in a suitable solvent such as water to give the ions Na+ and Cl-
