I'm not sure about part 1, you may need to google it, but part two is 11 protons, 11 electrons and 12 neutrons. You can find protons and electrons by just looking at the atomic number, and you can find neutrons by subtracting the atomic number from the atomic mass.
Answer:
What is the total number of valence electrons in the Lewis structure of nh4+?
Total valence electrons pairs
Total electron pairs are determined by dividing the number total valence electrons by two. For, NH4+, Total pairs of electrons are 4.

In order to represent a noble gas the Orbital notation should be equal to 2, 8 or 18 for eg. 1s²
I don’t know if this helps or not I’m still Not used to answering questions on Brainly These metals — beryllium, magnesium, calcium and strontium — react with hydrochloric acid to form a chloride and free hydrogen. Metallic magnesium when combined with hydrochloric acid, will naturally result in magnesium chloride -- used as a dietary supplement -- with the hydrogen being released as a gas.
hi
1 mile is 1 609 meters. (rounded).
As there is 100 centimeters in a meter, then
1 mile is 160 900 centimeter.
Then 1.5 miles , is 1 mile + one half so :
160 900 + 160 900 /2 = 160 900 + 80 450
= 241 350
1.5 mile is 241 350 centimeters.
please note that the value of a mile was rounded.
