Lithium is an element that has an electronic configuration of 2,1. So when forming bonds, it tries to release one of its electrons in the last shell to reach the octet state. Normally when atoms release electrons they get positive charge since the number of protons which bear positive charge, is higher than number of electrons which bear negative charge. So when reaching its octet state, lithium gains positive charge!
Hope this helps! Tbh am not good at explaining. If u have any doubts, ask me!
This is tue for many reasons help this works
Answer:
4.427 × 10⁵
Explanation:
In mathematics, rounding up a number is a way to get a more simpler figure but not too distant from the original number. Rounding up a whole number like this (442722) to significant figures means having only four non-zero digits in the figure i.e. 442722 ~ 442700.
This means that 442722 has been rounded up to 4s.f. Hence, to use scientific notations to represent our answer, we count the number of decimal places from right to left i.e.
442700 = 5 decimal places if the point is between 4 and 4 i.e. 4.427
Therefore, the figure 442700 can be written as 4.427 × 10⁵ using scientific notation.
S=50.05/32 O=49.95/16, S=1.5640625/1.5640625 O=3.121875/1.5640625, S=1 O=1.99, S=1 O=2 Empirical Formula= SO2
