The chart is about atomic structure: at the top, the left box is "nucleus" and the right is "electron cloud".


On the left, under nucleus, the two boxes are: "protons" on the right and "neutrons" on the left.  Under proton is elements which is given and under neutrons, it is "isotopes".


On the right, under electron cloud, the next box is "electrons" and then the lower box is "ions".

The table shows the classical model of atoms.

An atom is made up of a dense nucleus (left) and electron cloud (right) whirling around the nucleus.

Within the nucleus, there are protons (left) and neutrons (middle). Within the electron cloud are the electrons (right most).

If the number of neutrons is different but the no. of protrons is the same, that is called isotope (left). If a neutral atom gains or loses, it becomes an ion (right).

H2O2 is a polyatomic ion<br> ?
Bogdan [553]

Answer:

If you are meaning O2^2- ion, well, don’t forget that ions have a charge, that has to be specified when referring to them. It is a polyatomic ion just because it consists of more than one atom, irrespective of the fact that these atoms are of the same element or not. It was given that name because at the early times chemistry was founded as a science, it was found that with respect to other oxygenated substances, peroxides contained more oxygen than expected: Latin prefix per- gives the terms it is attached to the meaning of being increased, enhanced, and similar.

An element has an atomic number of 29. The number of protons and electrons in a neutral atom of the element are *
nasty-shy [4]

<em>The number of protons and electrons in a neutral atom of the element are;</em>

D. 29 protons and 29 electrons

<u>The atomic number of an element is equal to the number of protons in the nucleus of each atom of that element.</u>

<u>Thus copper has an atomic number of 29, all atoms of copper will have 29 protons.</u>

titration 25.0 ml of 3.4 x 10^ -3 M of Ba(OH) Neutralize 16.6 mL of HCL solution. What is the molarity of HCL solution?
marusya05 [52]
What we  are give: Concentration of base (CB) = 3.4 × 10^{-3}
Then convert all volume in ml to L.
Volume of base (VB) 25.0ml = 0.025L
Volume of acid (VA) 16.6ml = 0.0166L
Now that we have everything we use the formula CAVA=CBVB.
Make 'CA' the subject then solve. 
CA=\frac{CBVB}{VA}
