Answer:
The same number of electrons and protons.
Explanation:
Because a proton has a charge of +1 and an electron has a charge of -1, the ratio of protons to electrons must be 1:1 for the atom to be neutral.
(of a reaction or process) accompanied by or requiring the absorption of heat.
Answer:
Neutralization reactions occur when two reactants, an acid and a base, combine to form the products salt and water.
Explanation:
the inner core is the answer
Answer:
Yes
Explanation:
Qualitative data deals with the properties or qualities of matter. In qualitative studies, the aim is to understand all about the structure and properties of matter.
Some qualitative methods involve the use of radiation. A typical example of such is the X-ray diffraction. XRD is a qualitative method that can reveal the internal structure of a molecule as well as arrangement of atoms which are not hydrogen.
Also radiation is useful in quantitative measurements such as atomic absorption spectroscopy, spectrophotometry, etc.
