Chemical bonding occurs so that atoms can gain stability by filling this.
valence shell.
If a substance has a high melting point, is malleable, and conducts electricity it is probably this.
Metal
what is a charged particle called?
ion
What is subscript?
A number written below and to the right of a chemical symbol that shows how many atoms of an element are in a compound.
A compound dissolves easily in water and the solution conducts electricity. It is this type of compound.
What is ionic?
What is an isotope?
atoms of the same element with the same number of protons but different numbers of neutrons in the nucleus.
Without seeing the periodic table, state the number of electrons, neutrons and protons of Bromine.
e = 35
p = 35
n = 45
Explain why an ionic bond has a higher melting point compared to a covalent bond.
Ionic compounds are held together by strong electrostatic forces of attraction between oppositely charged ions. It takes a lot of energy to break the many strong bonds, thus the higher melting point.
State 3 usage of diamonds.
To cut hard substances. As jewelry. Used in audio equipment.
