Answer:
Group 18 elements
Noble gases
Explanation:
The gases in the last group of the periodic table exist in nature in uncombined state. Due to their nature of passiveness, they are called inert gases.
Other names include the noble gases. They are as follows
Helium
Neon
Argon
Radon
Xenon
These elements occur in as mono atomic atoms. Hence, they have an atomicity of 1
I think it's D ..... a membrane may contain hundreds of different proteins. ... Some integral proteins have only one segment that covers the whole membrane, others cross several times.
Answer
is: mass number stays 184, but atomic number changes.<span>
Beta decay is radioactive decay in
which a beta ray and a neutrino are emitted from an atomic
nucleus.
There are two types of beta
decay: beta minus and beta
plus. In beta minus decay (</span>atomic number Z is increased by one, new element is wolfram W) neutron is converted to a
proton and an electron and
an electron antineutrino.
In beta
plus decay (atomic number Z is decreased by one, new element is hafnium Hf), a proton is converted to a neutron and positron and an electron neutrino, so mass number does not change.
In thermodynamics, work of a system at constant pressure conditions is equal to the product of the pressure and the change in volume. It is expressed as follows:
W = P(V2 - V1)
W = 1.3x10^5 (2x6 - 6 )
W = 780000 J
Hope this answers the question. Have a nice day.
