The elements Li, C, and F, are all in the
period (row)
# 2 of the periodic table, and, in consequence, those atoms have two energy levels (main quantum number), n = 1 and n = 2, around the nucleus.
Do Li and Be have similar properties?
These pairs (lithium (Li) and magnesium (Mg), beryllium (Be) and aluminium (Al), boron (B) and silicon (Si), etc.) exhibit
similar properties
; for example, boron and silicon are both semiconductors, forming halides that are hydrolysed in water and have acidic oxides.
What do Li and Be have in common?
Only choice C refers to elements in the same group.
Lithium
(Li), sodium (Na) and potassium (K) are part of group I of the periodic table and are known as alkali metals and have similar properties.
DO AT and F have similar properties?
Terms. halogensGroup 17 (or VII) in the periodic table consisting of fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). They
share similar chemical properties
.
What elements have similar properties?
Elements in the same group of the periodic table
have similar chemical properties. Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals.
What are the similarities between hydrogen and lithium?
Hydrogen is not an alkali metal itself, but has
some similar properties due to its simple one proton (loctated in the nucleus)
, one electron arrangement. The lone electron exists in a s -orbital around the nucleus. For lithium, there are two 1 s electrons in an inner orbit and one 2 s electron in the outer orbit.
Are Li and be in the same group?
| 2 | 1A | Li | 2A | Be | 4A | C |
|---|
Is beryllium similar to lithium?
Lithium
and beryllium are the first elements of Group 1 and 2 respectively exhibit some properties which are different from those of the other members of the respective group. They both show similarity in properties of the second element of the following group.
Do I and CA have similar properties?
Calcium and potassium are both metals. … Calcium and potassium have a different number of valence electrons. Correct! Elements within in the same group/family have similar chemical properties due
to the fact that they have the same number of valence electrons
.
Which metal of second group is similar to lithium?
Learn more about
sodium
. alkali metal, any of the six chemical elements that make up Group 1 (Ia) of the periodic table—namely, lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
Which is the rarest element on the Earth?
A team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element
astatine
, the rarest naturally occurring element on Earth.
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 is Xenon so unreactive?
Xenon is one of the noble gases and it is so unreactive
because of the number of electrons that are present in its outer shell
. Since the outer shells of the noble gases are complete, they lack the tendency of the gain, lose, and sharing of the electrons.
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 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.
Are halogens P block elements?
p-block elements include the
group of halogens and inert gases
.
