Explanation:
Answer:
55 protons, 78 neutrons, 55 electrons
Explanation:
In a neutral Cesium atom we have 55 protons, 78 neutrons and 55 electrons. This can be found on the periodic table of elements.
Protons are the positively charged particles within an atom
Neutrons do not carry any charges.
Electrons are the negatively charged particles.
The amount of these subatomic particles can be obtained from the periodic table of element.
For a neutral atom, the number of protons and electrons are the same.
Since the atomic number is 55, it is also the number of protons in the atom.
Answer:
Answer A
Explanation:
atmosphere is made up of approx 78% N and 21% O2
In a gas molecules have to scatter off molecules to exchange energy in larger distances, so the probability of transfer is much smaller. Air is a bad conductor because, to conduct heat current molecules should absorb heat and transmit it to neighbor by vibrating.
Calculus, originally called infinitesimal calculus or "the calculus of infinitesimals", is the mathematical study of continuous change, in the same way that geometry is the study of shape and algebra is the study of generalizations of arithmetic operations.
