True, because a liquid can be taken and added, but a solid stay the same never losses and never gains
Answer:
Energy required to remove an electron from the atom.
Explanation:
Energy required to remove an electron from an atom describe ionization energy because in chemistry, ionization energy in is the amount of energy needed to remove electrons from the atoms or ions of chemical species.
Ionization energy increases as we move across the period of elements in the group and this is because electrons are bond tighter by high effective nuclear charge and ionization energy of elements increases down the group because electrons are bond together in lower energy orbitals.
Answer : The correct option is, (C) Both the atomic mass and the atomic number increase from left to right.
Explanation :
The general trend of atomic number and atomic mass in the periodic table is,
Both atomic number and atomic mass increase from left to right and decreases from right to left in the periodic table due to the addition of the number of neutrons and the number of protons in the nucleus.
Hence, the correct option is, (C) Both the atomic mass and the atomic number increase from left to right.
True
Explanation:
In the crystal of an ionic compound, the cations are surrounded by anions so that the charges of the ions are balanced. This very correct.
Ionic compounds are electrically neutral and forms by a charge balance.
- To form an ionic crystal, the charges overall must be balanced and the compound must remain electrically neutral.
- Equal number of charges on the metal and non-metal must cancel out to establish an electrostatic force.
