Answer:
D
Explanation:
heterogeneous mixture you can see the different substances that go into it.
homogeneous mixture you can't see the difference, the mixture looks like one substance.
Answer:
Discovery of neutron
Explanation:
Until 1932, the atom was believed to be composed of a positively charged nucleus surrounded by negatively charged electrons, after successful discovery of electron by J.J. Thompson and proton by Ernest Rutherford.
In 1932, James Chadwick bombarded beryllium atoms with alpha particles.
As Chadwick had previously seen in experiment conducted by Frédéric and Irène Joliot-Curie, they had bombarded a sample of beryllium with alpha radiation.
Chadwick repeated the experiment and observed an unknown radiation, this showed no deflection what-so-ever.
He repeated this experiment by bombarding other materials, like helium, nitrogen and lithium,
Finally, Chadwick found that this radiation was composed of particles with a neutral electrical charge and had approximate mass of a proton.
This particle was then known as the neutron.
The same column elements are called "groups" these are elements have the same outer electron arrangement which would lead to similar physical and chemical behavior. Hope this answers the question. Have a nice day. Feel free to ask more questions.
Answer: Metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and conduct electricity easily while making metal as good conductor.
the correct answer is a. the ability of electrons to flow throughout the metal.
Explanation:
Venn diagram is a pictorial representation with of circles showing the relation between two finite sets or things. the intersection of two circles conveys the relation between those sets or things.
here in the Venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circles represents the mixture of sand and salt.
<em>so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.</em>
