Question 4347: What are the coordinates of the vertex of the graph of f(x) = -3x - 11?

A) (3, 2)
B) (-3, -2)
C) (3, -2)
D) (-3, 2)

Answer 1

Strontium has an electron configuration of 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s². It is a metal with high metallic character and a relatively low ionization energy. Strontium has a larger atomic radius compared to elements to the left of it in the periodic table.

Step-by-step explanation:

The element strontium (Sr) is located in Group 2 and Period 5 of the periodic table. Based on its position, we can predict that strontium has an electron configuration of 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s². This means that strontium has 2 valence electrons in its outermost energy level.

Some properties that can be predicted for strontium based on its position are:

1. Atomic number: 38
2. Atomic mass: 87.62 amu
3. Metallic character: Strontium is a metal and has a high metallic character.
4. Ionization energy: The first ionization energy of strontium is relatively low.
5. Atomic radius: Strontium has a larger atomic radius compared to elements to the left of it in the periodic table.
6. Chemical reactivity: Strontium is reactive and readily forms compounds with other elements.
