What are the differences between isotopes and ions?
Isotopes are atoms that have the same number of protons but different numbers of neutrons. An ion is an atom or molecule with a positive or negative charge.
Is there any element discovered by an Indian?
NIHONIUM ORIGINS Element 113 is the first element to have been discovered in an Asian country.
What do you think was the reason for the names of the elements neptunium and plutonium?
Elements 93 and 94 were named neptunium (Np) and plutonium (Pu), because uranium was originally named after Uranus, and Neptune and Pluto are the next planets beyond Uranus, hence, the names neptunium and plutonium.
What are the differences of isotopes?
An isotope is one of two or more forms of the same chemical element. Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.
What do ions differ in?
Ions contain unequal numbers of protons or electrons . Atoms contain same or equal numbers of protons and electrons. Atoms have the same number of electrons and protons so t hey cancel out their charges.
Which is the oldest element?
Phosphorus
The oldest chemical element is Phosphorus and the newest element is Hassium.
How many isotopes does neptunium have?
There are 25 known radioactive isotopes of neptunium ranging in atomic weights from 225 to 244 with 5 of those as metastable isotopes. The most stable are Np-237 with a half-life of 2.14 million years; Np-236 with a half-life of 154,000 years; and Np-235 with a half-life of 396 days.
What color is neptunium?
silver
Neptunium is a silver metal and is very reactive, with four different oxidation states. When it combines with other elements it occurs as different colored solutions (purple, yellow, green and pink).
Who first discovered atoms?
The idea that everything is made of atoms was pioneered by John Dalton (1766-1844) in a book he published in 1808. He is sometimes called the “father” of atomic theory, but judging from this photo on the right “grandfather” might be a better term.
What are the differences between ions and isotopes?
Ion is an atom or mollecule section that have an extra electron (anion) or miss one (cathion) respect the number of protons, then it is electricaly charged. Isotope is an atom with a number of neutrons in its nucleous which differs from the stable condition or the most common condition,…
What’s the difference between anion and a cation?
An ion with a net positive charge is called a cation while an ion with a net negative charge is called an anion. Isotopes are different forms of an atom of an element, which have the same number of protons, but different number of neutrons in their nucleus.
Which is an example of an isotope of hydrogen?
Isotopes are atoms which contain a different number of neutrons. This leads to a significant difference in physical properties. For example, hydrogen is known to have three isotopes: hydrogen (0 neutrons), deuterium (1 neutron) and tritium (2 neutrons).
Are there any similarities between Hinduism and Buddhism?
After learning about the major differences between Buddhism and Hinduism, also learn about some of the similarities between Buddhism and Hinduism. There is idol worship in both Buddhism (Mahayana) and Hinduism. Both Buddhism and Hinduism give equal rights to men and women.
