Dipole interactions are observed in covalent bonds. In ionic bonding, permanent transfer of electrons occurs and due to this dipole-dipole interactions are not observed. In covalent bonding, electron cloud is shared between 2 atoms. If this electron cloud is not shared equally between them, polarities are formed in a molecule. And hence we say that the molecule is polar. For a molecule to be polar, there should be electronegativity difference between them. Atom with greater electronegative attracts electron cloud more towards itself whereas atom with lesser electronegative attracts electron cloud less. But there is no permanent transfer of electrons. Due to this electronegativity differences, atom with more electronegative gains partial negative charge and atom with lesser electronegative value gains partial positive charge. The charge is partial because there is no complete transfer of electrons.
Answer:
X 86 206
Explanation:
Radioactive atoms are nuclei that can under go disintegration to emit either an alpha particle, beta particle or gamma radiation. The process could be spontaneous or stimulated.
When a radioactive atom R 88 210 emits alpha particle, it would produce an element with atomic number 86 and mass number 206 i.e X 86 206. An alpha particle is usually a helium nucleus.

Newton’s first law state that an object in motion stays in motion unless acted upon force so the answer would be RESISTANCE
The forward and reverse reactions proceed at the same rate once at equilibrium.
Matter has mass and takes up space, which is called volume based on the amount occupied.
<h3>What is matter?</h3>
Matter is the basic structural component of the universe that usually has mass and volume (space).
Matter is everything around us and in our immediate environment that has mass measured in kilograms and occupies space or volume measured in litres or milliliters.
Examples of matter are:
- Carbon
- Metals
- Biotic or living organisms e.g. trees
According to this question, every state of matter such as solid, liquid, and gas has volume, but each state of matter appears a bit differently.
