Answer:
DNA is a vital for all living beings even plants.
Explanation:
It is important for inheritance, coding for proteins and the genitic instruction guide for life and its processes. DNA holds the instruction for an organisms or each cells development and reproduction and ultimately death.
A. True
you can see plasma. Or, technically, you can see the energy (light) given off by a plasma.
Answer:
Heat of vaporization.
Explanation:
the amount of energy needed to change the specific amount or gram of liquid in to gas phase is called heat of vaporization.
In this liquid is converted into gas phase as because after the boiling point addition of more energy will cause breakage of bonds present in between the liquid molecules which results in the vaporization of liquid.
A - 12
The amount of protons in a specific element do not change, for if the protons change, then the element themselves change. Therefore, no matter what, if the question specifies the element (i.e. Carbon) then the amount of protons will remain the same as seen on the periodic table.
Hope this helps!
Answer:
How many electrons are there in the lithium ion?
The battery goes on and on and on.
Each element have an electron configuration in depending of the principle (Hund’s rule , etc).
So by their atomic number tend to indicate the number of protons that are equal in a number of electrons.
So the atomic number indicate the numbers of electrons.
Atoms have direct stability as such lithium tend to be located in group 1A and period 2.
Lithium have the atomic number of 3.
So naturally their protons/number of electrons are 3.
The electron configuration is (LI) 1s² 2s¹ or [He] 2s¹.
To archive stability as any noble gas element HE , Then the lithium will form an electron to form a Lithium ion which is Cation LI+.
So by it the lithium ion had 2 electrons.
