Which element is Sonya most likely studying sulfur’s Neon NE
Which element is likely more reactive?
Hydrogen
is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.
Which element is likely more reactive and why Element 1?
Which element is likely more reactive, and why? Element 1 is more reactive
because it has fewer electron shells and is toward the top of its group
on the periodic table. Element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table.
Which metal is most likely to form more than one kind of positively charged ion?
Most
transition metals
differ from the metals of Groups 1, 2, and 13 in that they are capable of forming more than one cation with different ionic charges. As an example, iron commonly forms two different ions.
What’s surprising results is explained using this model?
Rutherford used positively charged particles to investigate the structure of the atom. The results surprised him, and he developed the atomic model shown below. What surprising result is explained using this model?
A few positive particles bounced back because they were pushed away from the positive center.
Which block element is highly reactive?
Complete Step by step answer: The elements of the group1 are alkali metals and
group2
are alkaline earth metals which have ns1 and ns2 outermost electronic configuration respectively. They are highly reactive metals with low ionization enthalpies.
What is the least reactive element in Group 2?
The least reactive element in group 2 is
beryllium
. Even at red heat beryllium will not react with water and it does not react with dinitrogen (N
2
).
Which is less reactive mg or Zn Why?
This shows
magnesium is more reactive than zinc
and both metals are more reactive than hydrogen. This third displacement reaction can be used for any metal that appears lower than itself on the table. … Adding a metal like copper to zinc ions will not displace the zinc since copper appears lower than zinc on the table.
What is the most reactive element in Group 2?
The alkali metals are the most reactive metals. Group 2 consists of the
alkaline Earth metals
. They are very reactive but less so than the alkali metals. Groups 3–12 contain transition metals.
Which is the least reactive metal?
Platinum
is the least reactive of all the options. Aluminium, iron are also formed in combined forms in the natural surroundings.
Will be form a positive ion?
The atomic number for bromine is 35, which means it has 35 protons in its atomic nuclei. A neutral bromine atom would also have 35 electrons. In order for a bromine atom to become a 1− bromide ion, it would have to gain an additional electron. The extra valence electron gives it a negative charge.
Which elements is most likely to form a positive ion?
Nonmetals are found on the right side of the periodic table.
Metals
form positively charged ions that are called cations. Metals make up approximately 80% of the periodic table and can be found on the left side and middle of the table.
Which elements can have multiple charges?
A few elements,
all metals
, can form more than one possible charge. For example, iron atoms can form 2+ cations or 3+ cations. Cobalt is another element that can form more than one possible charged ion (2+ and 3+), while lead can form 2+ or 4+ cations.
Which is the best conclusion about particles A and B?
Both particles are in the same atom. Which is the best conclusion about Particles A and B?
Particle A orbits the nucleus, and Particle B is located in the nucleus.
Which best describes Kai’s roundtrip?
Kai was 200 meters north from his house when he remembered he had to take some books to the library. It took him 200 seconds to do the round trip. Which best describes Kai’s roundtrip?
His speed was 2 m/s, and his velocity was 0.
What are the important changes in electronic devices?
Which important change in electronic devices, such as televisions and computers, is a result of the use of metalloids as semiconductors?
Electronic devices have become smaller
. This is how manganese appears in the periodic table.
