Hydrogen is in Group 1 of the periodic table. Which kind of bond would form between two hydrogens? (1 point)
O A covalent bond would form because the electron would be shared so both hydrogens have a full, stable shell.
O An ionic bond would form because both atoms are nonmetals.
O A metallic bond would form because both atoms are metals.
O An ionic bond would form because one hydrogen would transfer its valence electron to the other hydrogen to make a full shell.
I personally think it's answer one A covalent.
Yes, it is possible because they have similar intensive properties.
homogeneous mixture
Due to the repulsion between electrons, valence electrons will be arranged as far apart from each other as possible.
Neutral atoms of lead must have 82 protons. Ions must have 82 protons, as well.
Experiments that identified characteristics of atoms provided scientists with atomic weights and atomic numbers, which were used to organize the periodic table.

K and Cl
Polar sugar molecules dissolve in water, which is polar.
High temperatures mean more kinetic energy, which keeps sodium and chlorine ions from combining, which increases solubility.
It accepts protons and only partially dissociates in water.
PH3 is a stronger acid than NH3.
The scientist is investigating Charles’s law, which shows that temperature and volume are directly proportional.
It will likely be unreactive.
Student B, because of the law of conservation of matter.
The atoms have the same electronegativity.
bromine (Br)
No, it will not because iodine is less reactive than chlorine.
6H2O + 6CO2 → C6H12O6 + 6O2
+2
0.24 M
Tungsten (W) changes oxidation numbers from +6 to zero, so it undergoes reduction.
It has a higher boiling point than water, and it likely has stronger electrostatic forces between its molecules than water.
castor oil
Substance B has stronger bonds, and it takes more energy to undergo a phase change.
The student should perform multiple trials of the same experiment, then take the average of all of the results.
The results of several trials are all very close to each other, but they are noticeably different from the accepted value for the boiling point.

AB + CD → AD + CB
Oxygen is reduced, and iron is oxidized.
The bond energy used to break the bonds in hydrochloric acid and sodium hydroxide is less than the energy released to form the bonds in water and sodium chloride.
The total number of neutrons and the total number of protons are the same before and after the change.
Fission is a process in which a large nucleus is split into smaller nuclei.
A nucleus decays to produce a nucleus with one additional proton. Which type of decay did the nucleus undergo? beta-minus decay
Which type of decay is a form of nuclear fission? alpha decay
Increased mass results in reduced acceleration.
Speed is a scalar quantity, and velocity is a vector quantity.

Yes, covalent in H2 gas molecule
Watch out though. H is often ionic as in HCl or H2SO4 or any old acid
