What period is potassium k located?
Potassium (K) is a metal in Group I of the Periodic Table of the Elements. K has an atomic number of 19 and a molecular weight of 39.10 grams per mole.
As you move from potassium to krypton in the fourth period of the periodic table the elements will change from?
As you move from potassium to krypton in the fourth period of the periodic table, the elements will change from a metal (potassium) to a nonmetal (krypton). Potassium is a metal, while krypton is a noble gas and therefore considered a nonmetal.
What similarities do the elements of a particular period on the periodic table have?
The same number of shells
Which of these elements can be found in the same period as the element potassium?
arsenic 74.922 AS 33
What element can be doing in the same period as the element potassium?
sodium and lithium are both group 1 elements (like potassium)
What is the period of bromine?
The period of bromine is the fourth period on the periodic table. It is in the same period as other elements such as potassium, calcium, and argon.
What are the two highly reactive elements in period 4?
the metal potassium and the nonmetal bromine
What is the difference between period 4 and 5 on the periodic table?
There are 4 electronic shells in period 4 while there are 5 shells in period 5.Elements of period 4 are smaller in size as compared to elements of period 5.Example of period 4 element is potassium and period 5 element is tin.
What is the biggest and jump in atomic weights between consecutive elements on the periodic table Give the pair of elements and the difference in their relative atomic weights?
The largest jump in atomic weights between consecutive elements on the periodic table occurs between oxygen (atomic weight ~16.00) and potassium (atomic weight ~39.10), with a difference of approximately 23.10. This significant increase is due to the transition from lighter elements in the second period to heavier elements in the fourth period.
What is the element in the fourth period on the periodic table of elements used to be first to make fertilizer?
Potassium is the element that used to be first to make fertilizer.
Does each element have the same physical properties as other elements?
It depends. If the elements are in the same period or column, then there properties could be very similar. The number of protons is what determines the element. because no element has the same number of protons, no two elements have the exact same properties. For example, because Sodium (Na) and potassium (K) are in the same period, they are both metals, they both have one valence electron and both explode when they are put in water. The difference between these 2 is Potassium has a larger explosion because Potassium is more of a concentrate. The point is, two elements can be very similar, but no two elements are exactly the same.
Are there similarities of the elements across a period?
Yes, there are similarities among elements across a period in the periodic table. As you move from left to right within a period, elements typically exhibit increasing electronegativity, ionization energy, and effective nuclear charge, while atomic radius generally decreases. These trends occur due to the increasing number of protons in the nucleus, which affects how electrons are held and interact. Additionally, elements in the same period may display similar chemical properties, particularly among nonmetals and metalloids.
