The answer is: another name for groups of elements is family.
There are 18 numbered groups in the periodic table.
The elements in a group have similar physical or chemical characteristics and some groups have a specific name, for example group 17 (the halogens).
Elements in the group have the same number of valence electrons, for example, chemical elements in group 15 of the periodic table have neutral atom with a valence electron configuration of ns²np³.
Answer:
ΔG° is negative and ΔE° is positive
Explanation:
A galvanic cell produces electrical energy from spontaneous electrochemical processes.
In a galvanic cell, ∆E° is always positive since the reaction is spontaneous at room temperature.
Generally in thermodynamics, a negative value of ∆G shows a spontaneous chemical process. Hence in a galvanic cell, ΔG° is negative and ΔE° is positive.
Answer:
Lead forms an amalgam when filings are mixed with mercury and is also listed as a naturally occurring alloy called leadamalgam in the Nickel Strunz classification.
Explanation:
Brainliest please?
It could be Ne(Neon) or Ar(Argon) but the difference between both of them is that they are in different period Neon is in the 2 period and Argon is in 3 period
C) medium.
The medium of a wave is any substance that carries the wave, or through which the wave travels.Ocean waves are carried by water, sound waves are carried by air, and. the seismic waves of an earthquake are carried by rock and soil.
