Answer:
Explanation:
Lattice energy is the energy required to separate one mole of an ionic solid compound into its components gaseous cations and anions.
Due to increase in size of the ions, the lattice energy decreases while the lattice energy increases as the charge of the ions increases.
When the size increase, the distance between the nuclei also increase leading a decrease the force of attraction between the nuclei
Answer:
0
Explanation:
The overall charge on this atom is 0.
To find the charge on an atom;
charge = number of protons - number of electrons.
Note:
- Protons are the positively charged particles in an atom
- Electrons are the negatively charged particles in an atom
- Neutrons carries no charges on them.
Since the atom is made up of equal number of protons and electrons, the charge on it is 0.
If the number of electrons is more, the atom will be negatively charge but if the number of protons is more, it will be positively charged.
I think it’s 15cm
Might be 7cm
Answer:
113 miles
Explanation:
45.00 x 2.50= 1.12.5 so 113 miles in 2.50 hours
