Chemistry
1 answer:
Brilliant_brown [7]3 years ago
8 0

Answer:

2 protons per atom of Helium

Explanation:

The number of proton in a given element is given by its place on the periodic table which is for He 2 protons b/c the atomic number for He is 2.

Other Examples:

Hydrogen (H-1) or Protium has 1 proton b/c its atomic number is 1.

Magnesium (Mg-24) has 24 protons  b/c  its atomic number is 24.

Lead (Pb-207) has 82 protons b/c its atomic number is 82.

Uranium (U-238) has 92 protons b/c its atomic number is 92.

The periodic table order of arrangement of elements is based upon 'The Periodic Law'. => The chemical and physical properties of the elements is a periodic function of atomic numbers, or number of protons in the nucleus.

The electron configurations of some elements are given. Based on the electron configurations, which elements can likely form ion
sergeinik [125]

In the case of Zn, it is likely eligible for one charge, as its 3d is full, it can lose the electrons from the 4s2 level that it does to become Zn2+.

Iron has 6 electrons in the 3d energy level, which signifies that it would give up 6+2 to get to the next stable energy level. It is much convenient for it to give up the 4s2 and then one more out of the 3d6 to produce Fe2+ and Fe3+ respectively.  

Sodium has one electron to give away in the 3s energy level, as soon as it gives its one electron, it will look like Ne. In silver, the 4d10 energy level is full, it can only give up the 5s1 electron easily.  

In the case of cobalt, the electrons can be taken from the 4s2 energy level and then one more out of the 3d7 energy level, and after that more and more again. Thus, it can go from +5 to -1 charge, due to much more happening in the 3d7 energy level.  

Therefore, cobalt can likely form ions with multiple charges.

mihalych1998 [28]

Answer:

The answer is "11.07 g".

Explanation:

Isoamyl alcohol is a reagent restriction

Isoamyl alcohol Moles: 

= \frac{7.5}{88.15} \\\\ =0.085

Moles only with the shape of isoamyl acetate are equivalent to numbers.

Isoamyl acetate grams:

= 0.085 \times 130.19\\\\ = 11.07 \ g
