Answer: In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions. Metals are shiny.

Answer:
100.8 °C
Explanation:
The Clausius-clapeyron equation is:
-Δ
Where 'ΔHvap' is the enthalpy of vaporization; 'R' is the molar gas constant (8.314 j/mol); 'T1' is the temperature at the pressure 'P1' and 'T2' is the temperature at the pressure 'P2'
Isolating for T2 gives:
(sorry for 'deltaHvap' I can not input symbols into equations)
thus T2=100.8 °C
Answer:
An opinion is a statement describing a personal belief or thought that cannot be tested (or has not been tested) and is unsupported by evidence. ... Theories are not described as true or right, but as the best-supported explanation of the world based on evidence.
Answer: C. The specific heat of water is greater than the specific heat of metals.
The specific heat is defined as the amount required to raise the temperature of a unit mass of a substance by 1 degree Celsius.
This is expressed mathematically as
Q= mc∆T
Where Q is the energy/heat required which is measured in Joules.
m is the mass (grams)
c is the specific heat which is measured in joule/gram degree Celsius.
∆T- change in temperature
Substance which has a high specific heat require a lot of heat for its temperature to be raised by one degree. On the other hand substances with lower specific heat require only little amount of heat for its temperature to be raised by one degree.
Consider an equal mass of metal and water. If both are heated at the same time,the metal would become hotter than the water much faster. This is because the specific heat of the metal is lower than the water. Hence it requires only a little heat for its temperature to raised by one degree.
Thus we can conclude that the specific heat of water is much greater than that of a metal.
Answer:
B
Explanation:
because a periodic table shows the arrangement of element according to their atomic number and their valence neither
isotopes nor colour
