Hope it helps!!!!!!!!!!
Answer:
Yes, a body with a certain velocity can have an opposite acceleration, the acceleration would then be negative, since it is opposite to the direction to the velocity and also because the direction in which the acceleration is portrayed is on the left-hand side.
Hope this answer helps :)
Groups
Same number of valence electrons
Li, Na, K
Explanation:
A.
If the periodic table is not color coded, the groups of elements gives the arrangement of atoms with the same chemical properties.
All elements that are in the same group have the same chemical properties.
Periodic table groups are also called family. They are the vertical columns on the periodic table.
B.
Elements that same number of electrons in outermost shell have the same chemical properties.
The outermost shell is called the valence shell of an atom.
They are the shell containing the most loosely held electrons. Group 1 has just one electron in their outermost shell.
C.
Li Na k group 1
F Cl Br group 7
