One such grouping includes lithium (Li), sodium (Na), and potassium (K): These elements all are shiny, conduct heat and electricity well, and have similar chemical properties.
Which element properties are similar?
The reason for this is “valence electrons” – the electrons on the outermost shell of the atom. Valence electrons are the part of atoms that interact with the rest of the world. If two elements have the same arrangement of valence electrons , the world sees them similarly, and thus they have similar properties.
What are 2 elements that have the same properties?
As pictured below, notice how the elements lithium (Li), sodium (Na), and potassium (K) all look alike. They are all soft, silver metals. Since Li, Na, and K are all Group 1A metals, they all share similar chemical properties.
Do N and P have similar properties?
Nitrogen and phosphorous are part of the same ‘family’ on the periodic table, group 15, also called the nitrogen group. Since phosphorus is just below nitrogen, we can expect nitrogen and phosphorus to have some similar properties. They are nonmetals and have similar properties when making compounds.
What are 2 elements that have the same properties as calcium?
As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium .
What element has properties like helium?
Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne) , argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.
What has 12 protons and 25 neutrons?
#12 – Magnesium – Mg . It is the eighth most common element in the earth’s crust, but is the most commercially used element.
What are the 15 elements?
| Element/Symbol Atomic Number Mass | Nitrogen (N) 7 14.01 | Phosphorus (P) 15 30.97 | Arsenic (As) 33 74.92 | Antimony (Sb) 51 121.76 |
|---|
Which element has properties most like P?
Which element has chemical properties most similar to those of P? Arsenic is the correct answer but I do not understand why Arsenic is more similar to Phosporous than Nitrogen is to Phosporous. It seems that elements below the element being compared is more similar than the element above the element.
What is Group 16 called?
oxygen group element, also called chalcogen , any of the six chemical elements making up Group 16 (VIa) of the periodic classification—namely, oxygen (O), sulfur (S), selenium (Se), tellurium (Te), polonium (Po), and livermorium (Lv).
Which element is most chemically similar to oxygen?
Explanation: Oxygen is in group 16/VIA, which is called the chalcogens, and members of the same group have similar properties. Sulfur and selenium are the next two elements in the group, and they react with hydrogen gas (H2) in a manner similar to oxygen.
Why can’t two elements occupy the same box?
Multiple-Electron Atoms. All atoms except hydrogen are multiple-electron atoms. The physical and chemical properties of elements are directly related to the number of electrons a neutral atom has. ... This statement is known as the Pauli exclusion principle, because it excludes electrons from being in the same state .
What are three elements that have similar properties to calcium?
The elements found in group 2 of the periodic table have similar properties to calcium. Magnesium, strontium, and barium are a few of the elements in...
What gases are lighter than oxygen?
Hydrogen and helium are the most commonly used lift gases. Although helium is twice as heavy as (diatomic) hydrogen, they are both significantly lighter than air, making this difference negligible.
