How many protons are in hydrogen -2

Physics
1 answer:
skad [1K]4 years ago
5 0
The number of protons in the nucleus of an atom determines
what element the atom is an atom of.
If there's one proton in the nucleus of an atom, then the atom
is an atom of Hydrogen.
If there's any other number of protons other than one in the nucleus
of an atom, then the atom is an atom of some other element.  It's not
an atom of Hydrogen. 

If you say you have an atom of Hydrogen, then I know there's exactly
one and only one proton in its nucleus.  If you call it Hydrogen-2, I know
you must be talking about the Atomic Weight of the nucleus, and there
must be a neutron in there too. 

If you called it Hydrogen-37, I would know that there would still be exactly
one proton there, lost in a crowd of 36 neutrons.

What are the two forces that oppose each other while a star?
Rufina [12.5K]
While self-gravity pulls the star inward and tries to make it collapse, thermal pressure (heat created by fusion) pushes outward. These two forces cancel each other out in a main sequence star, thus making it stable.

How is energy transferred between trophic levels in a food chain?
Anastaziya [24]

Answer:

The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10% of the energy at any trophic level is transferred to the next level, the rest is lost largely through metabolic processes as heat.

In a cross over cable, signal gets transmit from one end of the device to the other.

Ngan has a weight of 314.5 N on Mars and a weight 833.0 N on Earth. What is Ngan's mass on Earth?
mr_godi [17]

Ngan's mass on earth is 85kg.

Ngan has a weight on Mars = 14.5 N

Ngan’s weight on Earth = 833.0 N

Ngan’s mass on Earth = ?

<span>Fg,earth = mg(earth)</span>

<span>M = Fg,earth </span><span>/ g(earth)</span>

<span>M = 833.0 N / 9.8 m/s2</span>

<span>M = 85 kg</span>
