<span>An atom is the smallest component of matter that keeps
all of the chemical properties of an element. Atoms merge to form molecules,
which then connect to form solids, gases, or liquids. Atoms are made up of
three basic particles: protons, electrons, and neutrons. Atoms have different
properties based on the order and number of their basic particles. Protons and
neutrons have accurate mass, about 1.67x10 -24 grams.</span>
The electronic configuration of a chlorine ion in BeCl2 compound is
[2.8.8]^- (answer B)
chlorine atom gain on electron form Be to form chloride ions
chlorine atom has a electronic configuration of 2.8.7 and it gains one electron to form chloride ion with 2.8.8 electronic configuration
Answer:
Groups show similar chemical properties about the elements
Explanation:
The periodic table is divided into groups and periods. Groups are vertical while periods are horizontal.
All elements in the same group possess the same number of outermost shell electrons. This number of outermost shell electrons controls the reactivity of the elements in the group.
Hence, groups show similar chemical properties of the elements in them, Groups separate elements into families which assist in the speedy study of elements.
Because Celcius is a larger amount than Fahrenheit. The units are farther apart.
