question 10 the halogens are a group in the periodic table that:

question 10 options:

have 7 electrons in the outermost "shell".

contain the element carbon

are metallic elements

are named after ms. j's favorite 80's band

The answer to your question is below.

Explanation:

Question 10.

Halogens are a group in the periodic table (VIIA), these elements have seven electrons in their outermost shell. Examples of halogens are Chlorine, Fluorine, and Bromine.

The correct answer is the first one.

Question 2.

The answer is false, in a neutral atom, the number of protons and electrons are equal but the number of neutrons is different.

Question 3

Nine is the atomic number of fluorine

Question 4

Group is correct

Question 5

True, elements with similar electron configurations are in the same group, so they have similar chemical and physical properties.

Question 6

Alkali metals and have one valence electrons.

Question 7

True

Question 8

8, elements with 8 electrons in their outermost shell are stable.

Question 9

6, due to oxygen has 6 valence electrons it is in group VIA.

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.
