Malleablity is a physical property so hence
D. Physical property is the answer
Chemical properties of elements are primarily determined by the electrons but not by the neutrons. Therefore, Isotopes can have different number of neutrons and electron,but not protons
Answer:
What do you mean Every force has a what?
Answer:
The assumptions of the Bohr model of the atom are:
- Atoms have a central nucleus with electrons in orbit about this nucleus.
- They must gain energy to jump to a higher level, and they release energy when jumping to a lower level.
- Electrons orbit the nucleus, but the orbits can have only certain sizes and energy values.
Explanation:
The Bohr model of the atom establishes that atoms have a central nucleus with positive charge and electrons (with a negative charge) in orbit about this nucleus. In the Bohr model, electrons move in specific orbits with a certain amount of energy and can't jump from one orbit to another around the nucleus. To jump to a higher level, they must gain energy or release energy when jumping to a lower level.
The Thomson model of the atom postulated that <em>atoms are solid spheres of matter</em> and <em>are made of positive material with electrons fixed in place in this positive material</em>.
