Answer:There are two types of atomic bonds - ionic bonds and covalent bonds. They differ in their structure and properties. Covalent bonds consist of pairs of electrons shared by two atoms, and bind the atoms in a fixed orientation. Relatively high energies are required to break them (50 - 200 kcal/mol). Whether two atoms can form a covalent bond depends upon their electronegativity i.e. the power of an atom in a molecule to attract electrons to itself. If two atoms differ considerably in their electronegativity - as sodium and chloride do - then one of the atoms will lose its electron to the other atom. This results in a positively charged ion (cation) and negatively charged ion (anion). The bond between these two ions is called an ionic bond.
Magnetic force, i did the test
Answer:
Silicon (Si)
Explanation:
Add the protons and neutrons mass to get the nucleus mass. Then you get number 14 and 28. looking at the periodic table we can see this matches silicon's atom mass and electron number
A valid lewis structure of SO2 cannot be drawn without violating the octet rule.
correct me if i’m wrong.
First you have to find the number of moles , then you have to apply stoichometry to find the number of moles of H2 gas , after that you can determine its mass.
