1. No two elements have the same kind of atom.
Explanation:
The correct of all statement is that no two elements have the same kind of atoms.
Every element have different atoms.
- Over a hundred elements have been identified by scientists.
- Atoms are the smallest particles that takes part in chemical reactions.
- Elements are distinct substances that cannot be split.
- Atoms of all elements do not have the same mass and volume. Isotopes are examples.
- It is true that atoms of all elements have different masses and also different volumes.
- The volume of an atom is function of the number of electrons it contains.

Answer:
oceans is the answer that I got
Answer:
Carbon
Explanation:
Carbon has four electrons in its valence shell, so it generally shares it in a covalent bond. This element needs four electrons to be stable, so it can form single (such as the bond with hydrogen), double (such as the bond with oxygen) or triple bonds (such as the bond with nitrogen).
It can also form bonds with other carbon, and they can form longs chains, that's why there are a lot of organic compounds (the compounds with carbon). Carbon can form rings too, such as in benzene.
Answer:
= 3132.9 Joules
Explanation:
- Kinetic energy is the energy possessed by a body when in motion.
- Kinetic energy is calculated by the formula; K.E = 1/2 mV², where m is the mass of the body or object, and V is the velocity.
- Therefore kinetic energy depends on the mass and the velocity of the body or the object in motion.
In this case;
Kinetic energy = 0.5 × 0.018 kg × 590²
<u>= 3132.9 Joules</u>
