Answer:
gallium
Explanation:
it is the old melting in a hot cup of coffee spoon
Answer: 
Explanation:
- The atomic mass of nitrogen is 14.0067 g/mol.
- The atomic mass of oxygen is 15.9994 g/mol.
This means the molecular mass of nitrogen dioxide is 
g/mol.
Dividing this molecular mass of the compound we need to find, we get that
.
So, the final answer is 
As - 8 dots and 3- charge, Se - 8 dots and 2- charge, Br - 8 dots and 1-, K - zero dots and +1 charge, Ca - zero dots and +2 charge, Ga - zero dots and +3 charge.
<h3>In the periodic table of the elements, what is its Lewis symbol?</h3>
The valence electrons of each element are represented by dots that surround their chemical symbol in a Lewis dot symbol. The Lewis dot symbol's dots correspond to the valence electrons, which correspond to the final digit of the element's group number as in periodic table.
<h3>What's an example of a Lewis symbol?</h3>
Two chlorine atoms, for instance, share one pair of electrons when they combine to form a chlorine molecule. According to the Lewis structure, each Cl atom contains one shared pair of electrons and pairs of electrons that aren't employed in bonds (known as lone pairs) (written between the atoms).

<span>Answer: option B. is much less than that felt by a single proton in a small nucleus.
</span>
<span /><span /><span>
Explanation:
</span><span />
<span>The strong nuclear force is one of the four forces in nature: 1) strong nuclear force, 2) weak nuclear force, 3) electrostatic force, and 4) gravity.
</span><span />
<span>Strong nuclear force is the strongest of the forces and is resposible for the attraction of the protons and neutrons in the nucleus, and so it is the responsibile for the stability of the atom nuclei.
</span><span>
</span><span>
</span><span>Neverthelss, it is also a force of very low range it can act only at very small distances. That means that the larger the nucleus the weaker the force.
</span><span>
</span><span>
</span><span>That is the reason for the unstability of the large atoms.</span>
Answer:
1. Methyl orange indicator: This shows pH in a colouess solution if it changes from colourless to red.
2. Phenolphthalein indicator: This shows pH of a coloured solution if it changes from purple to colorless.
