Answer:
to provide energy to the body and helps u grow stonger
Explanation:
<span>You can compare the strength of the hydrogen bonding by comparing the electronegativities of the other elements. All the four elements, Br, F, Cl and I belong to the same group in the periodic table: group 17 named halogens. Then the kind of bonding they form is similar: polar covalent. You must know the trend of the electronegativities in the periodic table. Electronegativity decrease when you down across a group. Then the electronegativity of F is the higher of the group (indeed, it is the highest of all the 118 elements) . The higher the electronegativity the stronger the attraction that the halogen attracts the electrons and the stronger the hydorgen bonding. Then, the conclusion is that HF has the strongest hydrogen bonding. </span>
1. If you find shielding that blocks gamma radiation,then it will most likely also block the other two types. (as the hardest radiation)
2. When nuclear radiation enters the tube of a Geiger counter, it the excited atoms of the gas contained in the tube. (this type <span>deposits all energy into a single atom)</span>
3 The particles that make up protons and neutrons and are thought to be basic units of matter are <span>quarks.</span>
Answer:
Aluminium have the most neutrons in the nucleus.
Explanation:
The number of neutrons in the nucleus can be calculated by subtraction of the atomic number from the mass number.
neutrons in aluminium nucleus = 27 - 13 = 14
neutrons in nitrogen nucleus = 14 - 7 = 7
neutrons in helium nucleus = 4 - 2 = 2
neutrons in fluorine nucleus = 19 - 9 = 10
