Answer:
the electron cloud model is the current model of atom
Answer:
d liquid
Explanation:
Bromine occurs in the liquid state at room temperature.
Bromine is the only nonmetallic element that occurs in the liquid state at room temperature.
The transfer of electrons is an ionic bond, therefore, we need to determine which substance includes an ionic bond.
CO2, is a covalent bond, which is the sharing of electrons, not transfer.
KBr, is an ionic bond, because (k) loses an electron to bromine.
So, our final answer is:- <span>(3) KBr</span>
They are pretty much the cause and effect. The independent variable that is being changed in the experiment, so it is the cause. The dependant variable is the result of change the independant variable, so the effect.
Explanation: • Electronegativity is the tendency of an atom to attract the electrons in a bond towards it. • Ionization energy is the energy that should be given to a neutral atom to remove an electron from it. The difference in the electronegativity between the two elements is quite small, but the main reason for it is because chlorine is one period below oxygen. Chlorine’s valence electrons are thus less tightly bound than those of oxygen, so they would have lower first ionization energy. Does sodium or potassium have larger ionization energy?
