Answer:
1) B
2) D
3) A
4) Ga
5) K
6)Po
7) Atomic size increases down the group
8) B<Al<Ga<In<Tl
9)Se<C<Ga
10) ionization energy is the energy required to remove electrons from the outermost shell of an atom.
Explanation:
In the periodic table, the properties of elements reoccur ''periodically'' throughout the table, hence the name 'periodic table'.
Ionization energy increases across the period hence the noble gas He has the highest ionization energy.
Since ionization energy increases across the period, group 1 elements possess the lowest ionization energy.
Since atomic size increases down the group and decreases across the period, gallium is smaller than indium, potassium is smaller than caesium, polonium is smaller than titanium and iodine is larger than bromine.
This explanation above justifies the order of increasing atomic radius of group 13 elements shown in answer number 8 above.
Since atomic size decreases across the period, the order of increasing atomic size shown in answer number 9 above is correct.
Ionization energy is the energy required to remove electrons from the outermost shell of an atom.
The structures and chemistry of individual hydrocarbons depend a large part on the types of chemical bonds that link together the atoms of their constituent molecules. Hydrocarbons are derived by chemical degradation.
The controlled variable is what he eats, the dependent variable is his weight.
a word of advice for your next ask, try to use better grammar and punctuation because this was kinda hard to follow.
Answer:
True
Explanation:
Technology has been mans best friend for a while due to the fact that they can make things to help others and create more jobs and help everyone overall.
Explanation:
You can test by putting sand in one cup and water in another. Then you put the thermometers in the cups. One you have done that you can use the heat lamp and put both cups under it for the same amount of time. After you do that and recorded your data you are done with the experiment.
Hope this helps :D
