Answer:

Because the student made use of scientific instruments in one case and his senses in the other.

Explanation:

Scientific experiments involve making observations, which is key to the outcome of any experiment. According to the scientific method, collecting of data is one of the steps in fulfilling the scientific procedure. One way to collect data is by using scientific instruments to measure, which is then recorded. This is the case for the WEIGHT of the sugar the student recorded.

Another way to collect data is by making use of the senses e.g eyes, nose, skin etc. to observe and record the perceived information. Therefore, the pieces of information collected by the student represent DATA because he made use of his senses and scientific instruments.

Element m reacts with fluorine to form an ionic compound with the formula mf4. the m cation has 18 electrons. element m is:____.

polet [3.4K]

Element M reacts with fluorine to form an ionic compound with the formula MF₄. The M cation has 18 electrons. Element M is Sn.

<h3>What is Ionic Compound ?</h3>

An ionic compound is defined as the compound made up of ions that formed charge particles when an atom loses or gains electrons.

<h3>What is Cation ?</h3>

Cations are positively charged ions. It forms when an element lose one or more electrons.

The cation which has 18 electrons is Sn. Sn react with fluorine to form an ionic compound with the formula SnF₄ because Sn is large and F is very small in size.

Thus from the above conclusion we can say that Element M reacts with fluorine to form an ionic compound with the formula MF₄. The M cation has 18 electrons. Element M is Sn.
