Answer:

When a substance heats up, the rise in temperature makes these particles move faster and bump into each other. Thermal energy is the energy that comes from the heated up substance. The hotter the substance, the more its particles move, and the higher its thermal energy.

Answer: Heat energy is another name for thermal energy.

Explanation:

As thermal energy comes from moving particles, it is a form of kinetic energy. Thermal energy comes from a substance whose molecules and atoms are vibrating faster due to a rise in temperature.

Which of the following isotopes would most likely be unstable and therefore radioactive?

svlad2 [7]

Answer: Mercury-194 is an unstable isotope and hence is radioactive.

Explanation: Mercury-194 is an isotope of mercury, having formula $_{80}^{194}\textrm{Hg}$

Number of protons in this isotope = 80

Number of neutrons in this isotope = 114

This isotope is radioactive in nature and under decay process by Electron Capture.

Electron capture reactions are the reactions in which a proton in a nucleus absorbs an electron and convert it into neutron. The resulting nucleus will have a decreased atomic number and same atomic mass.

Reaction for electron capture of mercury-194 follows:

$_{80}^{194}\textrm{Hg}+_{-1}^0\textrm{e}\rightarrow _{79}^{194}\textrm{Au}$

After a covalent bond has stabilized an atom, the atom will have

Dafna1 [17]

<em>Answer:</em>

The atom have a full valence electron shell.

<em>Explanation:</em>

My question is that why covalent bonds take place?

Every atoms tends to from bond with another atoms in order to get nearest electronic configuration of nobel gases. They become stable when their valence shell become complete. So when covelant bond forms between atoms, share electrons to each other and stabilize themselves.
