B. increase; decrease or are absent
In a liquid, the particles move around more than a solid, but way less than in a gas because there isn't that much space between particles.
When matter is a gas, the particles tend to move in a larger area and they tend to get very far away from each other. So, the space between particles increase and the attraction forces decrease.
Answer:
B 29 protons, 27 electrons
Explanation:
The given specie is copper ion:
Cu²⁺
We are to find the number of protons and electrons it contains.
The number of protons is the positively charged particles in the atom.
Electrons are the negatively charged particles in the atom.
The number of protons is the same as the atomic number
Atomic number of copper = 29
Number of protons = 29
Now;
Charge = Number of protons - Number of electrons
2 = 29 - number of electrons
-27 = - number of electrons
Number of electrons = 27
Chlorine is the most electronegative
Answer:
Sue was not right as wood is not a heat conductor and will not allow heat to pass through the spoon thus keeping the hand safe. In a meatal spoon, heat can pass through and burn the hand as meatal is a good conductor of heat.
